question about performance

[Ulrich Schmidt <u.sch.zw@...>]

Hi all.

I want to avoid any unnecessary table creation to keep the gc workload low.

Question: will the following code create the new table "{}" only if the
parameter "tbl" is nil OR will the new table created always and garbage
collected if the parameter "tbl" is given?

---8<----------------------------
function xx(tbl)
  local todolist = tbl or {};
  ...
end;
---8<----------------------------

tia.
