Why I use APL every day

I first met APL (A Programming Language) in 1968.

I've always used it a lot, and now I use it every day.

Many developers will never have heard of the language. Many of those that have, either love it (as I do) or hate it.

I think now is the time to explain what APL is, why I use it so often, and why I think that developers should take a look at it.

I hereby claim:

I am romilly on github.
I am romilly (https://keybase.io/romilly) on keybase.
I have a public key whose fingerprint is 878A 89AD 2AC2 E315 1E6C 5398 72CA 4FA2 E7CB 6E36

To claim this, I am signing this object:
