(1) Compiled benchmark. Template is parsed before the benchmark and
    generated ruby code is compiled into a method.
    This is the fastest evaluation strategy because it benchmarks
    pure execution speed of the generated ruby code.

(2) Compiled Tilt benchmark. Template is compiled with Tilt, which gives a more
    accurate result of the performance in production mode in frameworks like
    Sinatra, Ramaze and Camping. (Rails still uses its own template
    compilation.)

(3) Parsing benchmark. Template is parsed every time.
    This is not the recommended way to use the template engine
    and Slim is not optimized for it. Activate this benchmark with 'rake bench slow=1'.

Temple ERB is the ERB implementation using the Temple framework. It shows the
overhead added by the Temple framework compared to ERB.
