But increased readability increases maintainability. IMHO the equivalence of

sub fexists (-f $_[0] ? $_[0] : undef);
my $file = fexists ($p) // fexists ("$p.exe") // fexists ("$p.sh") // 
+…;

would involve lexical copies and a huge chain of defined ($x) ternaries.

So yes, many new features were doable in older versions, but they were ugly and error-prone.

I myself do NOT like OO programming. I need to understand how perl does it when dealing with modules that have no non-OO alternative, like DBI and Tk, but I still prefer to program non-OO myself. Moose however makes the threshold to actually *use* OO in perl in a way that does not constantly irritate me a lot lower (if it does take away the threshold at all). That on itself is worth considering, as that also makes the language more open to newcommers. OO-programmers get a head-start with Moose over the available OO techniques that the CORE has available.
