1. switched the following languages to use a magic heredoc token instead of a comment
2. there was one way to trigger ruby scope, by have a heredoc token of *_EVAL
now, there are two options:
a. foobar = <<-RUBY
b. eval <<-FOOBAR # works with eval, module_eval and class_eval
TODO:
* support <<-'HEREDOC' or <<-"HEREDOC" syntax for magic tokens for embedded languages
* support <<HEREDOC magic tokens for embedded languages
