IMHO, it is the most basic of all the string functions ("basic" and 
"frequently used" isn't the same thing).

Out of curiosity, I inspected Lua files in my local repository to find 
out the frequency of use of the string functions (including Lrexlib and 
LPeg ones):
    match   876
    gsub    260
    find    220
    sub     215
    gmatch   74
