Thanks a bunch, that's heaven-sent! :) Will try it immediately.

Did you run these with -i? Otherwise the interpreter is not really
compiling anything (it's all done lazily). To actually force the Pure
interpreter to generate the IR for a module when you run it in batch
mode and you're not actually computing anything, you can use a command
like the following:

pure -i set.pure </dev/null

This will force it to think it's in interactive mode, in which case it
compiles all pending definitions before it enters the read-eval-print loop.

Cheers,
Albert
