And yet it isn't ASM.

Probably because C had a lot of good features. Isn't PHP also in many
ways modeled after C?

I think, and I doubt I'm alone, that there a world of difference between
the classical goto syntax where you "goto" the line number and what is
now considered good goto practice by declaring a label and jumping to
it. Not only that but goto in modern practice is limited to where it can
jump by it's current scope (not sure if scope is quite the right word,
but you know what I mean).

Unmaintainable because of the ability to write cryptic code. There's
nothing cryptic about:
...code
goto cleanup:
...code
cleanup:
