Sure is. Everyone is welcome.

string.explode is not a standard Lua function but I can image what it'd do.
string.gmatch is not what you want here: you want string.match.
string.gmatch is for loops, like the one below which is what I'd write
for this task:
for k,v in string.gmatch(str,"([xyz])=(%d+)") do
ret[k] = tonumber(v)
end
The point is that there is no need to split str before doing the match.
