> seems the code uses nested named subs.

I was baffled at first, but you're right, the OP wasn't using proper indentation.

Worth noting that "newer" Perl versions have lexical subs via my sub name {...} constructs.

See perlsub#Lexical-Subroutines

Personally I'm still stuck to my $code_ref = sub {...} approaches.
