The intermittent not-working seems to be an artefact of the parameter
getting messed up (as I should have known!). Don't understand the bindings
well enough to see why the latter is happening.

Hi,
I'm trying to port the chessboard example from IUP to chicken. The C code
is here:
http://webserver2.tecgraf.puc-rio.br/iup/examples/C/cells_checkboard.c
I'm stuck when trying to add a draw callback - it crashes with
Error: (callback-set!) callback has bad signature
The code is here:
eans callbacks with a Canvas*
argument are unsupported in chicken-iup?

I have a list of words (182260 words, 1.6MB) that I need to read into

than do this every time the program is run, I want to serialise the
hashes and dump them to a file, and subsequently loading in the file
Also, serializing a hash dies when it hits the end (and attempting to
