That seems a bit odd to me, but if $^name merely causes a signature
to be generated that declares $name as a (lexically scope) parameter,
then it's just:
my $cl = { "$^name upcased becomes {$name.uc}" };
But perhaps for clarity you would just write:
my $cl = { "$^name upcased becomes $^name.uc()" };
