in reply to padding/substr quirk

You already got your immediate answer from Corion and Zed_lopez.

Next time, if a similar problem rises, or you need to find out the precedence or associativity of operators, where can you find the answer?

perlop

With the help of perlop, next time it is your turn to help others ;-)

    Or feed it to B::Deparse:
    $ perl -MO=Deparse,-p #!perl use strict;use warnings; use Time::localtime; print "substr month= " . (substr("0" . localtime->mon() + 1, -2)) . "\ +n"; print "substr day= " . (substr("0" . localtime->mday(), -2)) . "\n"; print "sprintf month= " . (sprintf "%02d", localtime->mon() + 1) . "\n +"; print "sprintf day= " . (sprintf "%02d", localtime->mday()) . "\n"; ^D
    which gives:
    use Time::localtime; BEGIN {${^WARNING_BITS} = "UUUUUUUUUUUU"} use strict 'refs'; print((('substr month= ' . substr((('0' . localtime()->mon) + 1), (-2) +)) . "\n") ); print((('substr day= ' . substr(('0' . localtime()->mday), (-2))) . "\ +n")); print((('sprintf month= ' . sprintf('%02d', (localtime()->mon + 1))) . + "\n")); print((('sprintf day= ' . sprintf('%02d', localtime()->mday)) . "\n")) +;
