To me, APL is logical--strict right-to-left precedence; simple array and
matrix operations.
I've long wondered if we introduced students to APL as a first language,
what our applications code would look like today.
My friend Bruce, called it "That Iverson Language".
It's interesting to note that the Iverson book was published in 1962,
but an implementation (under 7090 IBSYS) didn't come about until 1965,
although preliminary implementation as PAT had been done on a 1620 (!)
in 1963.
The extended character set was an important obstacle to its acceptance.
Besides keyboard (masking tape) and output (APL typeball, special
character generator, or having to substitute combinations of character),
many people were unwilling to even try something with a different
character set.
