First I tried to ship most of the logic towards executables and use
Method#for_define_method
andUnbindMethod#for_define_method
as thin wrapper aroundExecutable#for_define_method
.The result can be seen here: 7cd4315
When the need to support Proc again came up it was clear that shipping most of the stuff into executables was not quite doable, or at least I was not able to do it properly.
Therefore I moved it up into
Method
andUnboundMethod
where again we have nested conditionals (but at least no more nested conditionals in a big fat case statement)As for
BlockEnvironment::AsMethod#scope
I'm not sure if this should return nil or the scope of@block_env
. In the previous implementationdefine_method
for aBlockEnvironment::AsMethod
executable used nil as scope. Also when changing it to@block_env.scope
all ci specs are still passing so probably this means there are missing specs for that.
