I think that is the crux. Think of a label as the declaration
of a local variable. You can `goto l1` if and only `l1` would
be in scope if you replaced `@l1:` by `local l1`.
Viewed this way, the suggestion of replacing the syntax `@l1`
by `label l1` makes a lot of sense. The syntax highlighters can
make `label` obtrusively lurid, different from other keywords.
