Do you actually have any data how many % of Gecko devs would prefer
not using aFoo?
I strongly prefer 'aFoo' over 'foo' for the extra context that it gives
to the variable. If we want to change anything we should rather
introduce a separate prefix for output parameters.
Which part of this extra context is useful?
Repeating what Kats said elsewhere in the thread which seems to have
been completely ignored in the pile of messages here:
When debugging in a text based debugger such as gdb, sometimes you have
a variable called aFoo which has the wrong value, and with the existing
naming convention, you can quickly run "up" in the debugger to go to
caller frames looking for the first time the argument is called
something without an 'a' prefix, and then you look to see where the
value was computed. If we remove this naming convention, you would have
to do that work in every frame, which would make debugging the same
scenario much more time consuming.
Note that if you mostly use a graphical debugger such as Visual Studio,
you may not rely on this because the debugger would show you more of the
code in each frame, but I believe graphical debuggers are a niche among
Mozilla developers.
