* It's longer :)
* It defeats optimization, since you have to bounce through a "send"
call to get to the eventual call. In essence, send typically forces a
slow-path dynamic dispatch all the time. foo."something" would be a
literal dispatch to the target method.
* The default form of send routes around visibility. That's not always
what you want.
* On 1.8, send deepens the exception backtrace.

The syntax proposed is basically a quoting mechanism for literal
method calls. It doesn't replace send, it just expands what you can do
with direct call syntax. send changes the dispatch logic in subtle
ways.
