The quotes are optional. I was curious about this too and checked that both variants (with and without quotes) work correctly.
this is too arbitrary. the syntax needs to be consistent. i would prefer int arg without quotes and string arg with quotes. if arg is pseudo variable, it should be written without quotes, because it is a VARIABLE.
I am not sure about this, I guess this is a question for Daniel.
daniel?
