Why does it make no sense? Have you never had to
scrape a web page or read a CSV file?

Duh. I took for granted you knew how to convert
an string to an integer.

So this proposal would only apply to string literals
at compile time, not running programs?

And I want the same error to occur if my CSV parser
tries to convert '123 456' into a single number.
I don't want it to assume the number is '123456'.
