[int_19h]

Programmers also write something like *[3]int instead of "pointer to array of 3 integers" in most PLs.

(Modula-2 tried the latter, but it didn't stick.)

[cubefox → int_19h]

Yeah, though such special symbols are less common. I think they are still too common though. E.g. using the unnecessarily obscure "if (A) B" instead of "if A then B".
