# Should 1st Class Methods be part of Ruby proper?
#
# Perhaps the best solution would be using the notation
# <tt>::ameth</tt>. This would require some minor changes
# to Ruby, but with few backward incompatabilites if
# parantheticals revert back to the actual method invocation.
# Although this later stipulation means capitalized methods
# would not be accessible in this way b/c they would intefere with
# constant lookup. It's a trade off. ...
#
# Current Proposed Alternate
# ----------------- ------------------ -------------------
# Foo.Bar() method call method call method call
# Foo.Bar method call method call method call
# Foo.bar() method call method call method call
# Foo.bar method call method call method call
# Foo::Bar() method call method call 1st class method
# Foo::Bar constant lookup constant lookup constant lookup
# Foo::bar() method call method call 1st class method
# Foo::bar method call 1st class method 1st class method
#
# Then again this dosen't address bound versus unbound.
