AFAICT, the only unambiguous syntax is the following:
`initial_token` [arglist] `separator` [chunk] `final_token´
or
`initial_token` [arglist] `separator` [explist] `final_token´
with `final_token` ~= `initial_token`, and various restrictions on the
individual tokens to avoid ambiguities.
It can be reduced to
`initial_token` [arglist] `separator` expression
if you allow only one return value.
