[PD] expr size() refuses some array names

I think the best thing is to tell [expr] to expect a symbol in its
first inlet (the name of the array), and then create the symbol by
other means.  This more in keeping with the normal usage of [expr] and
friends anyway, I think.

[symbol $0-foo]
 |
[expr size("$s1")]


has always worked for me.
