this is not particularly important but i accidentally typed 0b12 in the repl and discovered this:

i couldn't find an existing issue on this topic, and i haven't investigated it much, it smells like something is catching a tokenizer error and interpreting it as "this is incomplete"
0b12 and 0o1239 also appear to be highlighted as a single number. i'm guessing pygments is highlighting 0b1 and 2 as separate tokens, both numbers, and the result looks like a single token due to the lack of a separator
