It would appear that nobody has learnt the lesson that C++ got from
grabbing Ada generic syntax (which in Ada is a straightforward and
logical application of constraint syntax) without thinking.  It has made
a messy grammar quite messier.

Lua is not a line noise language.  That's not an invitation for pulling
in the favorite line noise constructs from some other language because
it causes almost no conflicts with preexisting line noise.
