hey, i stepped into the same trap a while ago. interpret
doesn't throw an exception but returns nil on error.

a partial solution would be to have Process.compile throw an
exception instead of returning nil, but then the error would
still be printed. as a real fix, the primitive could stuff
the error message into a variable, e.g. lastCompileError,
which the exception then can access.
