APL was terse.

You could do amazing things with very short source code.
Extremely well suited for scientific programming.
(I used it on a timesharing terminal at Goddard Space Flight Center half a 
century ago)

It had a lot of operators.  So much so that it had to expand the character 
set.  Typically, it was used on a Selectric based terminal, with a special
