suggestion: table.remove and non-integer keys

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

Hi all.

I deal with some really large strings i have to sort in some way and 
finally create a concatinated result string. The string content doesnt 
change.
I store the strings in a table using non integer keys. (eg.: file names)
I dont want to make copies of the strings because they are large.
Finally i create a sorted table with integer keys and do a table.concat 
to create the
really large result string.

Now the problem:

i want to move a string without making a copy
from a table '[string] = string"' to a table '[int] = string'.

table.remove() doesnt work because it requests integer keys.

So i do a simple asignment;
    td[int] = ts["key"];
    ts["key"] = nil;

As far as i know this creates a copy of the value-sting.

My question/ suggestion:

Why not allow string keys in table.remove?
Simply remove one entry from the table without shifting around other 
entries.

Any pros and cons? I overlooked something?


Thanks.
Ulrich.
