Unary +@ can't be defined for Symbol?

class Symbol
def -@
[ self ]
end
def +@
[ self ]
end
end
p -:a # => [ :a ]
p +:a # => :a

What’s the problem here?

Problem parsing plus and colon probably. I noticed that:
p(+(:a)) #=> [:a]
which does decidedly look bad. No problem when the symbol is stored in
another value, as:
x = :a
p +x #=> [:a]

Thanks, Kent.

I hope it can be fixed. Kind of puts a big damper on what I’m working on.
