I don't think it's that ...

Anyway, I think the following is simple enough that I'll just put it
in the public domain. It allows me to use perl in the .cpu file -
well, in the file that the .cpu file is generated from (or, for that
matter, in any other text file). One needs to escape characters that
are special in perl strings - mainly dollar.

Application looks as follows:

(... normal cgen stuff ...)
! for my $i (@list) {
!    for my $j (@otherlist) {
(... normal cgen stuff, with vatiables $i and $j ...)
!    }
! }
(... normal cgen stuff ...)


and then

domac.pl xxx.cpu.in xxx.cpu

Script attached.
