Maybe I read the original lesson wrong, but I understood the point of
that article to be how to use Lisp macros (which he renames 'spel's so
as not to confuse people).  I'm new to Ruby, but it seems that Ruby
doesn't offer such a mechanism.  Most solutions here seem to use
method_missing to handle the new features, but that really isn't the
same as a macro.

Does anyone know if macros will be introduced into Ruby in 1.9 or 2.0?
Even something like Dylan's macros would be great.

The latest description of Ruby 2.0 I know of doesn't mention macros at
all. http://www.rubygarden.org/ruby?Rite  Do people here think macros
are not useful?
