Do you have an opinion @jneen? The idea makes sense to me but the overall reduction seems pretty small. |

@ashmaroli I realise you split #1430 off from this one so that #1430 could more easily be merged. I'd still like to discuss that one but having looked at this, I think it's helpful in more clearly expressing intent. And, as you pointed out, it reduces memory usage! Thanks for submitting it :) |

…-ruby#1416) Rouge makes use of dynamic loading of files at various points throughout its codebase. In these instances, the method `Kernel#__dir__` is used. This commit instead uses module constants to more clearly express intent and, as a bonus, reduce the number of object allocations required.

__dir__allocates a new string on each call. Using this method in string interpolation(
"#{__dir__}/....") or path based methods (File.join(__dir__, ....), etc) results in duplication of the newly generated string.This allocation can be reduced by stashing the value in frozen module / class constants.
