Oh, my version is an error. I implemented the macro before definitions in
(some) expression contexts were a thing.
Andy did a marvellous thing implementinf the new letrec: if it is possible,
letrec will have no overhead. It also automatically handle dependant clauses:
even though it might seem counterintuitive, the guile-proper version will do
the right thing always. The syntactic differentiation mine does is just there
for our feeble human minds, at least with regards to what guile-proper is doing.
So TL/DR: guiles way is the correct way.
