Hi Oleg,
From what I understand, you are using a list of integers to encode a path to
a subterm. This is a practical and lightweight implementation, but less
type-safe: it is easy to encode annotations that do not correspond to any
value. Also, it cannot guarantee, with types alone, that every

Hi,
How do I use Text.Regex.PCRE to get information on multiple matches? For
instance, in ghci I get this error message:

Hi,
I am working on a project that features a few modules with inter-dependent
states. It is expected that some of the modules import and use some of the
stateful functions from other modules, and simultaneously, need to manage
the state of their own. I need to make a design choice as to whether

Hi all,
I am trying to simply download a web page using the HTTP library. It
works fine with http://www.google.com; but a redirecting page like
http://gmail.com; creates an error. Code is at

It is even simpler than that. The type determines the return value.
axxfayyf =~ a..f :: Bool
True
axxfayyf =~ a..f :: Int
2
axxfayyf =~ a..f :: String
axxf
axxfayyf =~ a..f :: [[String]]
[[axxf],[ayyf]]
axxfayyf =~ a..f :: [MatchArray]
[array (0,0) [(0,(0,4))],array (0,0) [(0,(4,4))]]
The problem is that any page that that responds with 301.302,303 or
307 and redirects to an https is rejected by the library.
The code that does the rejection is in Network.Browser on line 865.
It only accepts http:. Why was this design decision made? It makes
it impossible for me to use this
Nevermind I see that you already knew that. But it is very cool anyways,
I'm totally going to use regexes more often now that I've discovered it.
