I will look at this -- compiler can behave stangely on wrong
code.

Yes, currently only in interpreter. There is a workaround which
I used in few places:
fooz ==> 2*z
fooz where z ==> x^2
that is omit parameter list when defining macro, and then provide
parameters using 'where'. Not nice, but helps if macro body is
large.
