I did not reproduce all the details from the thread, but I tried to
capture the essential points. Please point out omissions and errors.
Thanks,
What I’m missing about Function.name is that you can only specify it
using function literals (at least, currently in Firefox I think that is
the case). It would be nice if you could also either set this with
either the Function constructor, or after the object has been created.
This is functionality that is currently missing, so that function
constructors are second-class citizens compared to function literals.
(By the way, while you’re at it, it would be nice if the constructor
also allowed closures to be specified, because that is also something
functions created with the Function constructor unfortunately cannot do).
Also, it would be nice if when a function is declared as follows:
yyy.xxx = function() { … }
yyy = { xxx: function() { … } }
That in both these cases the function’s name property would be ‘xxx’ as
well.
Both these would aid debuggability of functions. Currently we have code
that looks like this to aid stack trace debugging:
xx.core.Events.createEvent = function xx_core_Events_createEvent() { … }
This makes the function show up with the name
‘xx_core_Events_createEvent()’ instead of ‘anonymous()’ in Firebug,
which I guess is an improvement, but I think this is a terribly ugly way
to go about it :). So it would be nice if I could just leave the name
out and it would still show up as ‘createEvent()’ (I can make do without
the xx.core.Events part).
