This is more a Bigloo problem than a Hop problem.

Bigloo provides a TAKE function. It is exported by the standard library.
If you use that function, everything runs fine. You error is intercepted
and reported correctly.

The srfi1 library also exports a TAKE function (this is confusing, I
agree). This is the one that is not correctly implemented. Actually, the
assumption was made that the SRFI-1 implementation is safe and the
library is compiled in unsafe mode. The assumption is wrong so two
versions of the srfi library must be built. I will change this as soon
as possible.

Thanks for this report.
