Jean Boussier c91c266872 Enable Style/ExplicitBlockArgument cop
This reduce the stack size which is beneficial for
exceptions performance.

See: https://gist.github.com/byroot/cb3bcadcc3701c2518d002fb8d3a4e7a

However the cop is unsafe because it might change the block arity,
so it can run into some false positives.
