That's only the obvious approach if you say @ is a comment delimiter.

Consider:

10 SIM

where SIM is a mis-typed SIN.
The current code treats this as a bad line and skips it; aggressively recognizing numbers as unnumbered number literals would cause this to be interpreted as 10.

I decided not to use comment delimiters because most commented program listings that I've seen don't have them (not needed because those listings were written to be read by humans only), or they use arbitrary ones, including @ but also ; or : etc.
