Yes, maybe that can help. But that was not the point (I think). I know
that the syntax foo is not visible outside the let but it is not
problem since 'f' already used it an is visible outside : that's what
I want.

The thing that puzzles me is that if I replace the define-syntax in
the let by a load of a file that contains exactly the same syntax
definition it doesn't work no more : guile 1.4 says me that square is
unbound.
