The idea behind 'with' is that the block is executed while holding
(i.e. 'with') the resource.
I think the '-ing' form of the example templates is a holdover from
the days when the PEP used the 'do' keyword - I find that past tense
or noun forms tend to read better than present tense for custom built
with templates named after the action that occurs on entry:
# Past tense
with locked(my_lock):
with opened(my_file, mode):
with redirected_stdout(my_stream):
# Noun forms
with my_lock:
with open(my_file, mode) as f:
with extra_precision():
with decimal.getcontext() as ctx:
The place where the '-ing' form still makes some sense is when the
template is named after the action that will occur at the *end* of the
block:
with closing(some_gen()) as g:
with releasing(some_rsrc()) as r:
Cheers,
Nick.
