I have a request.
Unrelated to the current pull.
I saw in the chat people mention +: something like a verb and assign operation bundled in one.
v+:3
is similliar to
v:v+3
?
can you explain more about this situation?
what kind of verbs can i use with it?
will it work with functions?
is it worth mentioning somewhere in the help?

thanks
i'll move the line about ?[] further down, as it's not a special form like cond, return, etc

v+:3

yes, practically like v:v+3 but it can be a bit more efficient by reusing the memory allocated for v

what kind of verbs can i use with it?

all primitive verbs

will it work with functions?

no, not with other kinds of functions. for instance:

v{x+y}:3 /can't do that
f:+; v f+:3 /can't do that either

worth mentioning somewhere in the help?

maybe. idk how to describe that concisely.
