Closures upon closures is not intrinsically easier or harder to keep organized than subclasses upon subclasses.

They just organize naturally in different ways. If a clean OO model fits your problem, then OO naturally channels you. If it doesn't, then using closures is better than trying to fight OO into an imitation of what you would do more naturally with closures. Particularly so in Perl where writing any OO involves so much infrastructure.

BTW your extra method-call hooks could be replaced with a single method that is intended to be called from subclasses with SUPER. Less code and infrastructure, same result.

[choroba]: No, if there are no threads, then the user wants to use MCE. If there are threads, the user can choose.
[1nickt]: choroba Understood. I'm wondering about the logic in a cpanfile. If the perl doesn't support threads, it's easy: require MCE. If the perl does support threads, as you say the user has a choice, so require both? Or, assume that irrespective of the choide
[1nickt]: ... choice, the threaded-perl user *probably* wants to use threads, therefore only require threads and leave MCE out, allowing the user to manually install if desired?
[choroba]: just require any of MCE and threads. Not sure if that's possible in the cpanfile, but should be possible early in the Makefile
[1nickt]: The app expects threads as default anyway, right?
[choroba]: that's true
[1nickt]: expects threads *to be* the default
[1nickt]: I think cpanfile can handle the logic. testing now.
