Problem: Leaking memory when there is a cycle involving a job and a
partial.
Solution: Add a copyID to job and channel. Set references in items referred
by them. Go through all jobs and channels to find unreferenced
items. Also, decrement reference counts when garbage collecting.
Problem: Double free when a partial is in a cycle with a list or dict.
(Nikolai Pavlov)
Solution: Do not free a nested list or dict used by the partial.
Problem: When a dict contains a partial it can't be redefined as a
function. (Nikolai Pavlov)
Solution: Remove the partial when overwriting with a function.
Problem: Using string() on a partial that exists in the dictionary it binds
results in an error. (Nikolai Pavlov)
Solution: Make string() not fail on a recursively nested structure. (Ken
Takta)
Problem: When binding a function to a dict the reference count is wrong.
Solution: Decrement dict reference count, only reference the function when
actually making a copy. (Ken Takata)
Problem: Get E923 when using function(dict.func, [], dict). (Kent Sibilev)
Storing a function with a dict in a variable drops the dict if the
function is script-local.
Solution: Translate the function name. Use dict arg if present.
Problem: Using ":call dict.func()" where the function is a partial does
not work. Using "dict.func()" where the function does not take a
Dictionary does not work.
Solution: Handle partial properly in ":call". (Yasuhiro Matsumoto)
