Hi Jim,


My understanding is that because these are object methods, the
prototypes actually were not providing the checking benefits [see
PERLSUB(1) (section "Prototypes")] -- this is evidenced by the fact that
some of the prototypes I removed actually had the wrong number of arguments!

Now that the subroutines are being dynamically called by function
references, the checking also appears not to apply [see the same source].

There was also a more concrete reason: the setup code will automatically
set up multiple environment dependencies and pass each of their vars as
an individual parameter. Accomplishing this was [seemingly] impossible
with the prototypes in place.

Additionally, there seems to be a consensus among perl devs that
prototypes are generally harmful: see this post (by my colleague) for
example: http://www.perlmonks.org/?node_id=406231


If this is okay, attached is a version of the patch with this commit
separated out and the explanation in the message.


Thanks,
- Jamie
