Fair enough, it is a pseudo-function.  I suppose I was thinking of t =
{explode(multiple()),10,20}; it is a pseudo-function because although
normally it means function(...) return ... end, it would then have
special semantics inside a table constructor.

Actually, the usual rule is confusing for beginners and experts alike
- that {multiple(),10} behaves differently from {10,multiple()}, and
that you have to use () for the second case to only insert the first
value returned.
