Comment (by ryandesign@…):

 lua is one of those languages that seems to break backward compatibility
 with each version. Not every lua-using program is affected, but it seems
 like some always are. This is exactly the kind of software that should
 have multiple simultaneously-installable (sub)ports so the user (or the
 other program) using lua can choose which version they want. It's the same
 reason why we offer multiple versions of python, ruby, php, clang, gcc.

 Dave, I am definitely in favor of "moving forward" as you said above, just
 that I have a different definition of "moving forward" than you do. To me,
 "moving forward" is providing and maintaining the multiple versioned ports
 of lua, so that even old software can be built with lua support. Removing
 old lua ports would be moving backward, to me, in that it would break
 ports that require those old versions of lua. Even if there aren't many
 ports in MacPorts today that require old versions of lua, it's possible
 new ports will be added that require old lua, or that some of the ports
 that currently declare a dependency on just "lua" actually require an
 older version and have just not been tested with newer versions yet. (One
 example I'm currently working on: #39074.)
