[PD] expr size() refuses some array names

It does take $0 and $1 etc, it just means a completely different thing 
than $f1, $f2 etc.

$1 is the creation argument of the patch containing [expr] and it 
expands to its value, just like it would in any other object.

And regarding array names, [expr size("foo$1")] does create and does 
work (also with $0)

The problem is not specific to dollar signs: the problem is that expr 
won't accept a name (for the array in this case) that starts with a 
number, or that contains an aritmetical operation sign. Which, besides 
not allowing for names that are legal in Pd, seems like an error in the 
parsing process, because it seems it applies the same rules inside 
quotation marks that it would apply without quotes.

Maybe the same problem would apply to variables (meaning [value]s) as 
well as arrays, I don't know - and maybe the workaround you suggested 
applies to that case...
