Ah, I should read more carefully, and sorry to use the F-word so late
in the programming century. But the numerical guys will tend to read
it as multiple-indexing.

It's a little awkward with string keys : t["one","two"], but not awful.

Given f() that returns multiple values, is t[f()] intended to access
all those values? Because then we have the classic
propagation-of-multiple-values problem that gave you such grief with
string.gsub.

I think I'd need to see more elaborate code snippets to decide if this
is useful, or just cute...
