void= buffer.append( text_str, ... )
Ability to modify a string 'in place', without creating new entries all
over. This is basically the same as "str ..=" (C-like in-place operator
syntax) would be.
Usage: gathering strings together, big data. Perhaps there's a table
function for this, I'll see.. (yes, 'table.concat' but I still needed to
craft a temporary table to collect the strings first)
Current implementation: str= str..whatever
or: table.concat()
Question: does anyone know of the performance difference between
'table.concat' and regular appending?
