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.
