which seems to have been done before
or came up independently
in D, you have slightly more fine-grained options
<open file>
scope(exit){<close file>}
<actual use of file starts here>
<generate opening xml tag>
scope(success){<generate closing xml tag>}
scope(failure){<some cleanup>}
<contents inside that tag are generated here>
a spontaneous reaction:
In J, I’d like to use generators like
fileworker =. workfile thatone
'exitstatus result' =. verb_using_file&.fileworker arg_of_verb
or
memlocker =. lockmem mutex
'exitstatus result' =. atomic_verb&.memlocker arg_of_verb
[do we even need exitstatus?]
one could even make them generate adverbs
but using &. makes the intent clear
so I’d prefer not adding too much syntactic
sugar – but as always, there are different
tastes and digestive systems (called minds) …
so the argument should be passed and the cleanup
assigned as the obverse, potentially supplementing
the result with an exit status value/error code
would that interfere with your ideas?
