Well, maybe I shouldn't be trying to enforce types in method calls,
but I do. I have a tag <@ISINT> which takes a string and returns a
boolean based on whether the string represents an integer.
Maybe I should have written the tag to accept an array in addition to
a string, and process accordingly, but I didn't. It's easy enough to
loop through the array and pass each element as a string for testing.
But the problem occurs when I have a null array (zero rows by 1
column). I typically was testing for an array be counting rows, but
the null array throws an exception with a bad reference. Hence, I
need to test both rows and columns. No big deal, but it is self-
documenting to have an <@ISARRAY> meta tag than an expression.

All Witango vars are arrays
when you do <@var local$name> it is the same as <@var local$name[1,1]>
And isarray doesnt imply having data just would mean that it is an
array.
and since you need the name of the array, and you get that with
@numrows
Just makes me wonder if this is really needed
just my view point

I would like to have a metatag <@ISARRAY SCOPE=scope NAME=name>.
Current workaround: ("<@NUMROWS ARRAY=name> >0" AND "<@NUMCOLS
ARRAY=name> > 0")
