in reply to map a list

I'm a fan of the ternary operator, but i think an approach like this would be clearer:
# LHS = Left-hand side # RHS = Right-hand side my $s = 'a,b=c,e=#f'; my %h = map { $_ .= "=fn($_)" unless /=/; # add a RHS s/#(\w+)/fn($1)/; # change the RHS '#' notation to the ' +fn' notation split( /=/, $_, 2 ); # return the LHS=>RHS mapping (delim'd + by a '=') } split /,/, $s; # split on commas to get the strings for the pai +rs
