in reply to Format a list with commas and "and"

What about this?

sub andify { return '' unless @_; return $_[0] if @_ == 1; local $" = @_ == 2 ? ' ' : ', '; $_[-1] = 'and ' . $_[-1]; return "@_"; }
Fixed squiggly brackets and should be $" not $,.
Fixed comma placement.
Got rid of blackberry comment.
Handled null case.
Changed regex to concatenation
