Support local labels.

A whishlist item.

Some assembers (such as nasm) support local labels (https://github.com/yasm/yasm/wiki/NasmSyntax#labels). Basically labels that start with a dot are forgotten about any time a label not starting with a dot it read. This allows using nice short labels inside of a function.

; My function
foo:
    mov cx, 100
    .label:
        noop
        loop .label
    ret

; Other function
bar:
    cmp ax, bx
    je .label ; Refers to label below.
    noop
.label: ; No collision.
    ret

This is a really convenient feature, sometimes loop is really the best label name.

Also interesting but less useful is that nasm allows access to local labels from outside via label.locallabel syntax.
