hugs crashes if one tries to define unix:

unix = undefined

INTERNAL ERROR: compileGlobalFunction

I presume you have -F set to run the C preprocessor on source files aha, this is true indeed (i'd forgotton about it as it is in my shell configuration file).

(and unix is predefined in there to 1). So the real bug here is that

1 = undefined

gives the above error.

...

another interesting thing occurs if the following is added:

...

f = test' unix test' = undefined

then one gets an undefined variable:

ERROR "test.lhs":11 - Undefined variable "unix"

however this does not seem to happen if the ' is not there

The pair of single quotes protects this unix from the preprocessor. i see. i never realized that, it could have made an interetsing obfuscated haskell entry :-)
