This bug happened to appear two days ago and never disappear (both in
version 6.4.0.13 and 6.5.0.1) in my codebase, however if I copy the minimal
relative code into a fresh file, it disappears. In the original one's REPL,
it disappears too.

In the case of double-click to select a word, you could implement it
via the keymap in a t
Hello,
I try to find an easy way to add the general mouse selection system
(double click on a word will select it for example) on a text-field gui
component.
In the multi file search tool of Drracket, text-fields have this
feature, but by looking the source code :

I think this is not quite Matthias's point about laziness. The point
is that Haskell programmers generally (are supposed to) program as if
they don't care what order things are evaluated in, so the ability of
macros to change that order isn't relevant to them. (Of course, this
is foolish for a numb
Hi.

What do you mean by the 'nature' of the evaluation? Do you thnk that
macro change the operational semantics of the language, or what?...

I don't see how a lazy language would let me implement my own version of
`let`. Care to enlighten me?
