I have not had a chance to try this yet but it sounds very promising.

This is a guess but I think you can't 'my' the fft variable and then use
it as a reference. Because it is looking for main:: which your my'd
variable will not be in that namespace, or any namespace for that
matter. If you are working under use strict trying our'ing it instead,
or just removin
I am trying to use a code reference from within a function to
recursively call a given separate function...
#--- LIKE THIS --vv
sub hello {
my $name = shift;
return "Hello, $name!\n";
}
sub foo {
my($f, @args) = @_;
return &$f(@args);
}
print foo(\&hello, "world");
#---^^
the above work
