Changes (by nthiery):
* commit: => 68d43b83000550b26ae1dcf2ee9f8e127f16fde2
* work_issues: => failing tests, memory usage
Comment:
The current implementation more or less works. However, given the usage of
an action and the current implementation of actions, this will probably
leak memory if a lot additive semigroups are temporarily constructed.
There are also some failing tests.
Still, reviewing the rest can start.
