The trouble is that a lot of Lua code would mysteriously break, since
we have internalized the 'only expand at end' rule.

So there was a proposal to make ... mean expand:

{f()...,1,2,3}

which would also apply to function arguments.

this seems feasible... is this rule acceptable for the mainline of lua language?

maybe we can accept a convert script to convert old code to new rule. IMHO the history should not become the stumbling block.
