I understand. I was following LJ section 15.2. So in the console I typed: bc=:
<“
When I tried calling which works as <“0 y but must use 0 bc y
which totally confused me. Further down on that section I see that (quote):
The argument to be supplied to the conjunction can be a noun or a verb, and on
the left or on the right. Altogether there are four similar schemes:
x (C N) means x C N
x (C V) means x C V
x (N C) means N C x
x (V C) means V C x
the last one shows my use case, but doesn’t explain why.
Also, just saw the response from Adrien.
Thank you both!
