My apologies if this is the wrong place to suggest this, but how about adding a keyed format specifier for string.format?

To me,

string.format("%(foo)s  = %(bar)d", {foo =  "variable", bar = 22})

which I stole from Python, would be very handy and fits comfortably into the primitive way I think about Lua.

This would be pretty easily done w/:
string.gsub("%(foo)s = %(bar)d", "%%%(([^)]+)%)", {foo = "variable", bar = 22})

you could abstract it a bit...
