Adding a '+' method to Kernel for symbols would reduce code clutter
but still ultimately end up requiring conversion from symbols to
strings to do
the append operation, right?

(ruby 1.9 is allowing me to do more with the ?! chars than I think I
remember 1.8 where I think I remember getting some errors around
this. )

I would not normally care much, or feel a particular need to
understand what is going on under the hood, but I have a performance
issue right here and this happens be one of the things I'm working on.

comments?

then, what would be the best form to add two symbols together (ending
up with a symbol again)



quick check:
sym1,  sym2= :abc_defg?, sym2 = :xyz
puts   (sym1 + sym2).to_s
=> <main>': undefined method `+' for :abc_defg?:Symbol (NoMethodError)
