I propose we use "shape" as the standard term to
describe the set of dimension extents for a piddle.
E.g., roughly and without error checking:
pdl> sub shape { pdl($_[0]->dims) }
pdl> $a = zeros(3,2,5);
pdl> p shape($a)
[3 2 5]
This follows the notation in a number of other
array languages such as Fortran 95 and later,
http://gcc.gnu.org/onlinedocs/gfortran/SHAPE.html
I think standardizing on this terminology could
clarify documentation and be useful in the PDL
Book endeavor.
Thoughts?
