Subject: rdoc fails to parse complex method def

rdoc can't handle the following code and crashes:

def (config = "").write(arg)
   concat(arg.to_s)
end
(from mkconfig.rb)

The internal error was:

/usr/local/lib/ruby/1.9/rdoc/parsers/parse_rb.rb:1941:in `parse_method': 
undefined method `name' for #<RubyToken::TkLPAREN:0x4ad4e0 @text="(", 
@char_no=4, @line_no=1> (NoMethodError)
         from /usr/local/lib/ruby/1.9/rdoc/parsers/parse_rb.rb:1640:in 
`parse_statements'
         from /usr/local/lib/ruby/1.9/rdoc/parsers/parse_rb.rb:1573:in 
`parse_toplevel_statements'
         from /usr/local/lib/ruby/1.9/rdoc/parsers/parse_rb.rb:1405:in 
`RDoc::RubyParser#scan'

The problem seems to be here:

         name = name_t.name

Not all tokens have names.
