[PD] expr table functions

[Jamie Bullock]

Hi!

Has anyone successfully used the table functionality offered by [expr]?
I can get simple table lookup to work as follows:

float x	      symbol y
|	      |
[expr $s2[$f1]]


But I can't get any of the table functions to work. For example, [expr
size($s1)] gives the following console output:

error: expr: syntax error
 expr size($s1)
... couldn't create


I am using expr 0.4 with PD 0.37.1 on Linux.

Thanks,

Jamie
