I think they were something like this:
# Merge two hashes, allowing the latter hash to override values in the
first.
# I sometimes use this to combine a hash of subroutine arguments with
default values:
my %args = (%defaults, @_);
# Map one list of values to another, but only include "true" values.
# The trick is using the empty list () as opposed to undef:
my @output = map { frobulate($_) || () } @input;
Thanks for a great meeting everyone!
