But I did propose that some sort of string splitting be made standard.
The Lua string routines are not minimal: you can do gfind, match, 
gmatch in Lua if you have find; you can do find and gsub in Lua if 
you have sub; you can do sub in Lua if you have byte and char.  

Should not the criteria for admitting a new routine to the standard 
library be: 
(a) you can't do it purely in Lua, or
(b1) you can, but it is inefficient, and
(b2) the task is a very common one.
