hi tony---thanks. I will keep an eye on the docs (presumably streams).
from a novice end-user (not developer) perspective, solving the specific
snippet that I noted would be great in the documentation pages. regards,

I see. thank you. it was a little confusing. it was right under the
header
Advanced Options for Reading CSV Files

I am a complete julia novice, so I may simply not understand the following.
when I type
> julia> d=readcsv("myfile.csv")
> julia> typeof(d)
Array{Any,2}
I think this shows that it interprets the header as data, and sets the
columns to be of type "any". alas
hi doug---and vice-versa. it's interesting that a core function (reading a
.csv file) would not be in a native julia library. when are you switching
your students to julia? regards, /iaw

ladies and gents---I am not (yet) a julia user.
may I suggest adding more examples into two places where julia users will
face starting hurdles?
[1] the I/O docs of julia. like, reading and writing csv files that are
compressed and decompressed on-the-fly, even if not in the ultimate
a double hull. many, many full *working*
standalone examples are the next best thing for me.

Julia is only at version 0.4 (well, soon). It's too soon to expect
miracles. :-). however, I want to restate an old suggestion. a language
should have as few surprises as possible. this applies not only to
features, but also to performance.
not nagging, but curious---is there an expected arrival date (plus minus)
posted somewhere?
not a
real pull-request and wouldn't be merged, but it's an effective reminder.
perfect. I will do this later in the week.

to work also with the (Pipe,Process) tuple. otoh, maybe doing this
with a Handle simply automates this everywhere?! not sure. I can't
weigh in on a discussion. I just don't know enough.

writing clear.
in the absence of ability to change github to allow specific insertion
points, I wonder if we want to branch the docs and request that
comments be left in a particular color (say, red).

dear julia users: beginner's question (apologies, more will be coming).
it's probably obvious.
I am storing files in compressed csv form. I want to use the built-in
julia readcsv() function. but I also need to pipe through a decompressor
first. so, I tried a variety of forms, like

functions that expect a part of open. julia should be smart enough to
know this.

I am reading again about the type system, esp in
http://julia.readthedocs.org/en/latest/manual/types/ . I am a good guinea
pig for a manual, because I don't know too much.
a tuple is like function arguments without the functions. so,
mytuple=(1,ab,(3,4),5)
is a tuple. good.

dear julia experts---I am about to start teaching my MFE class. Mostly, my
students will do programming with data. My transitioning plan is as

standard.) Next year, I am planning to encourage julia equally with R. In

would it make sense to warn the user about slowing down global variables
from julia itself? and/or about other slowing constructs that are almost
always beginner's mistakes that julia can guess at? my guess is that if
a program does not reuse a global outside its context, this is defacto a

I am still a lurker, not a user---although I hope to adopt julia in a year

a class will force me to switch to julia.

You mean it's better than even the R guys?
Maintaining culture in the long run will be hard.

one should not have to write both server-side cgi programs and client-side
javascript for one application. one should not even have to learn
javascript...

there are no good web development language environments (server, browser)

I hope julia will wipe out my need for c++, perl/python, and R.

in perl, there is a nice package feature that allows parsing text like
latex macros which have matching parens.
use Text::Balanced qw(extract_multiple extract_bracketed);
does something like this exist (already) in julia ?
true beginner's question: after I have defined a function (possibly
multiple dispatch), how do I remove it again??
I with it had been something more unique...like JuliaL . too many google
hits on julia.
