Maybe I'm missing what you're trying to do. But, why not just use built-in ERB?

ERB.new(File.read(path_to_template)).result(binding)

Oops, I forgot to mention that I prefer using Haml/Sass than ERB. Here's what I'm trying to accomplish.

Haven't got any code, but why use __END__? Why not just heredocs? (See below)
Also, even that way, no need to place to IO.read(caller.first.split(':').first).split('__FILE__').last - the global constant 'DATA' is set to whatever is after __END__ in a script.

templates = <<END @@ index %html %head $title %body % Hello, World. END
This method was taken from Sinatra.

I'm wanting to use templates in a one-file script I'm working on so I can generate HTML/CSS. Does anyone have any tips on how to make it faster/slimmer/better?
