Exegesis 4 ...
In Apocalypse 3, Larry introduced the // operator, which is
like a || that tests its left operand for definedness rather
than truth.
What he didn't mention (but which you probably guessed) was that
there is also the low-precedence version of //. Its name is err:
Operation High Precedence Low Precedence
INCLUSIVE OR || or
EXCLUSIVE OR ~~ xor
DEFINED OR // err
This is in the "Read or Die" section of E4 if you want to read more.
