Always ``list``-cast the ``mngrs`` input to
|
||
|
|
``.trionics.gather_contexts()`` and ensure its size otherwise raise
|
||
|
|
a ``ValueError``.

Turns out that trying to pass an inline-style generator comprehension
|
||
|
|
doesn't seem to work inside the ``async with`` expression? Further, in
|
||
|
|
such a case we can get a hang waiting on the all-entered event
|
||
|
|
completion when the internal mngrs iteration is a noop. Instead we
|
||
|
|
always greedily check a size and error on empty input; the lazy
|
||
|
|
iteration of a generator input is not beneficial anyway since we're
|
||
|
|
entering all manager instances in concurrent tasks.
