Retrieving elements of function returns [message #41817]

Hello All,

Bit of an odd request this. I've recently found that I can take the
nth element of a returned array by enlosing the function in brackets and
then appending an array subscript:

n_pix=(size(grid))[1]

which is a bit neater than

n_pix=size(grid)
n_pix=n_pix[1]

I've had a look though the online help, and I can't decide if this is a
reasonable thing to do or not -- primarily I'm concerned that this is
some sort of undocumented feature which may disappear in later versions.

Can someone reassure me that it's ok?!

Cheers,

Ben
