Summary: won't open files with $0 in file name

Initial Comment:

In Pd-0.40-2, it won't open a file that has a $0 in the filename.  This works fine on Pd-0.39.2-extended-rc4 and Pd-0.39-2.

This is on Mac OS X/Intel 10.4.9

so this time to concentrate on objects with "$0" in them, e.g. [parent$0]
or [array-with-$0]

these do not load anymore on recent versions of pd, since the $0 is
expanded at runtime, therefore pd is in fact looking for an object e.g.
[parent1004] (which it cannot find).
i do not see any solution for this, unless you do not want in-symbol
expansion of $args (which i think we all agreed is a good thing to have).

obviously one could make a special rule for $0 in object names (this is:
the 0th argument of an object box; all other arguments should be treated
"normally"); but i do think that this is counterproductive ($args are
complicated to understand anyhow; adding exception rules will make things
only worse)

could you add an example? i am not sure how you try to open the file:
- via the file->open menu?
- via a message?
- as abstraction?
- ...?


what is the expected behaviour in the light of the extended
$arg-expansion?
(e.g is it related to the [parent$0] problem? there won't be a solution
for this until we there is an escaping mechanism)


i am not sure i can reproduce any problem with the attached file on
0.40-1: it downloads as "array" (without extension), so i had to rename it
to array.pd; but i guess this has exactly undone the problem you described.
