[PD] expr size() refuses some array names

[Matt Barber]

http://crca.ucsd.edu/~syadegar/expr.html

specifically:

--------------------------------------
Tables and variables can be accessed the same way one dimensional
arrays are accessed in C; for example, "valx + 10" will be evaluated
to the value of variable 'valx' + 10 (variables have to be defined
using the 'value' object) and "tabname[5]" will be evaluated to be the
5th element of table "tabname". The name of the table can be a
variable as well; for example "$s2[5]" will be evaluated to be the 5
element of the array whose symbol has been passed in inlet 2.
