I second that.

I've encountered IDL software where the developer decided to make EVERY
parameter a keyword parameter, even the required ones that you have to enter in
every time. I found all that typing quite a pain. (On the other hand, I also
remember the bad old days, before IDL keywords were invented, and all
parameters were positional, even if you had twenty of them!)
