Can add a method similar to the C ++ printf function?
a = printf("\d, \s, \x", 123, "string", 456)
return a = 123, string, 0x1cb
You can already do similar with the scripting languages' own string objects/functions. What do you need that cannot be done already?
This is what I've been using in my projects, works very well, i.e. recognizes most sprintf placeholders, and the license is permissive:
