Hi Lee,
Personally I think JSwat does the job right in that you can break the
code and get a look at local variables. There has also been release a
'debug-repl' which allows you to halt execution and jump into a REPL,
like so: http://georgejahad.com/clojure/debug-repl.html. There exists

Hi Ben,
I think we often get the impression that functional programming is
directly connected to monads, but in practical terms the important
concepts are pure functions and persistent immutable datastructures.
The learning curve when coming from an imperative language, lies (for

Hello, I just was to lazy to get my Javadoc, so I wanted to list the
methods of an object from the 1.1-REPL.
I got different results when mapping .getName or #(.getName %) over

expectations are wrong. Would you please rectify?
Hi,
Java methods are not clojure functions. To treat them like first-class
functions you have to wrap them in clojure functions as you did in
your second example.
For your actual task: you might want to look at clojure.contrib.repl-
utils/show.
Sincerely
Meikel

Hello,
is there a possibility to reload a clj-file that has been provided at
the REPL-start via -i filename.clj ? (It doesn't have a name space.)
This would save me to provide a namespace in the file an thus type (ns
my-ns) after every REPL start.
Thank you and greetings,

Would :deprecated be a reasonable thing to include in a function's

pairing it with some programmer friendly message (hey, use bar

Or... maybe 10,000 lines of XML as metadata! :-)

But using symbols for something like this is a bit contrived anyway.
Maybe, but I've seen it in other Common Lisp books/tutorials before.
e.g. I'm sure PAIP was one of them.
Part of the motivation is that CL symbols always compare with EQ and
EQL, whilst strings are not required to do so:
