I think they were something like this:

# Merge two hashes, allowing the latter hash to override values in the  
# 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!
