Yeah, and for extra bonus points: construct a function with a "range"
qualifier (see :help :function and :help E124) and/or a user-command
with a -range attribute, probably defaulting to current line (see
:help :command and :help :command-range) and update your mapping to
invoke them. If you define both in a single script (e.g. in your vimrc
or in an ftplugin), it is possible to define a public (i.e.
user-facing) command which calls a private (i.e. script-local)
function.

Best regards,
Tony.
