[Jprogramming] language proposal: {::: and {::.

['Pascal Jasmin' via Programming]

consider the adverbs

X =: (&({::))(@:[)

Y =: (&({::))(@:])

These are useful for extracting an item from either x or y parameter lists (that may be boxed) tacitly

2 Y i.3 equivalent to (2 {:: ]) i.3

shorter and doesn't require parentheses if not the right most part of a fork.

I'd propose {::: as a built in for Y, and {::. as built-in for X

Though it is more typing to use compared to Y and X, it would allow for 0 spacing readability of adverbs/modifiers.

You cannot type 2Y (as legal expression/name).  You could type 2{:::

Forks are more readable when all/as much as possible of the spaces separate the tines.
