Currently these are the signatures for tostring and type:

tostring (v) -> string

type (v) -> string

Would it hurt to change them to:

tostring (v, ...) -> string, ...

type (v, ...) -> string, ...

(Similarly for math.tointeger/math.type/io.type, maybe also os.getenv, etc)
Vararging a parameter list is a breaking change, even if it is fully
backwards compatible with one-argument calls, because


will currently keep only one of the return values of "myfun". You will
need to insert parentheses in order to preserve that behaviour.

In my reply to a previous post [1] of yours, I referred to a package
that inter alia offers item-by-item evaluation of a one-argument function
over a vararg.


Assuming my proposal goes through, print(...) -> io.write(table.concat(table.pack(tostring(...)), "\t"))

It'd be nice if we could get rid of print().
