Hmm.  I suppose I'm of a slightly different opinion--to me
list.map &:symbol

is less clear than
list.map(:symbol)


If we were required to write
list.map &:symbol.to_proc

then I would be more easily convinced that list.map(:symbol) is too 
implicit.  So for me it's implicit already.

I'm not too worried about the run time slowdown...so many methods are 
already special cased...it doesn't seem to be a too large concern to the 
core guys...
