You can set the hash up at the beginning from multiple strings using map.

perl -e '%h = map{split /X/} q{fooXbar}, q{bishXbash};
print qq{$_ -> $h{$_}\n} for jeys %h;'

produces

bish -> bash
foo -> bar

If you have to add another key/value pair subsequently you will have to use intermediate variables to avoid the clobber.
