What do you do if you want to disambiguate the return type? I suppose `intFromString` works. I'm not sure what I chose `intOfString`. It's not because I'm French!
You would declare the type of the returning value:
(i :: Int) = fromString s
Although once in a while it's useful to make a short synonym for disambiguating the type, x_of_y is certainly not a short synonym, so it's not commonly used.
And as a consequence, Rust has it standardized as "i = from s".
