So if python converted:
debugLog( <# ‘format string %r’ % (expensive(),) #> )
Into:
def __tmp__():
yield ‘format string %r’ % (expensive(),)
debugLog( __tmp__ )
Then debugLog can detect the generator and call __next__ only if logging is
enabled.
I guess at that point its the same as using the lambda but you have the syntax
sugar
of Steven’s <# … #>.
