Thanks. I came up with:
function gisub(s, pat, repl, n)
pat = gsub(pat, '(%a)',
function (v) return '['..strupper(v)..strlower(v)..']' end)
if n then
return gsub(s, pat, repl, n)
else
return gsub(s, pat, repl)
end
end
This might have been asked before, but why didn't you guys make
`gsub' also accept `nil' for the final parameter?
