[Haskell-cafe] Is there some place where I can find the
hs-curses doc ?

Those are actually unrelated.
"initscr"# is a GHC extension, producing a memory address (effectively
an Int) of a string in the .rodata section, like a C string, and usable
as arguments for C string functions.
(#const FOO) is a directive to the hsc2hs preprocessor, instructing it
to find the value of FOO and insert it in the source code here.

Don't - mailman does it automatically.
