Thanks! I'm guessing you mean Grape and not Gradle?
Small suggestion - can we cache places where respond_to is used in the hot path? (so not to affect performance)

[raszi]

Yes, I am sorry, it was late when I opened the pull-request yesterday. :)

[raszi]

Sure, I'll adjust my PR and I'll do a force push to fix the git commit messages.

I just verified whether it is necessary or not:

Warming up --------------------------------------
         respond_to?   216.089k i/100ms
              cached   261.694k i/100ms
Calculating -------------------------------------
         respond_to?      5.608M (± 5.8%) i/s -     28.092M in   5.026076s
              cached      8.979M (± 7.9%) i/s -     44.750M in   5.018407s

Comparison:
              cached:  8978741.0 i/s
         respond_to?:  5608259.8 i/s - 1.60x  slower

@jondot sorry, but with the current implementation I can see no good place to put the caching in place.

If you have any recommendations I am open for that.
