[LanX]: $; exists, so does the glob
[GotToBTru]: $; is "useful for emulating multi-dimensional arrays in Perl4"
[LanX]: i.e. &; is parsable
[LanX]: it's sometimes useful in P5 too
[LanX]: but I don't understand the question...
[GotToBTru]: okay, I see what it does
[GotToBTru]: you;ve answered it .. the expression is meant to be evaluated as written, it is not a symbol for a special operation
[LanX]: '&;@' is a parsing error
[GotToBTru]: by itself, yes, but used in sub pre(&;@) not so
