I'm not. I'm all for doing things to save developer time, but I think the symbol to proc thing is super lazy. I see it a lot in projects I work on from other developers and I usually remove it when I see it. So I wrote a textmate find and replace macro to undo them. You can download it here or copy the following source into a file called whatever.tmMacro.

Once its installed you should be able to do Command-Shift-P and replace all the symbol-to-procs in the current document with their regular proc equivalent.

I've tested it with the following scenarios:

1
2
3

%w(My super cool array).map &:to_s
%w(My super cool array).map( &:to_s )
%w(My super cool array).map(&:to_s)

If you have any other crazy way of passing in your symbol to proc, let me know. Of course if this macro destroys your computer or sets your hair on fire I take no responsibility, just ask my illegitimate children.
