Vocabulary
kernel

Inputs and outputs
objan object
quota callable
currya curry


Word description
Partial application. Outputs a callable which first pushes obj and then calls quot.

Class description
The class of objects created by curry. These objects print identically to quotations and implement the sequence protocol, however they only use two cells of storage; a reference to the object and a reference to the underlying quotation.

Notes
Even if obj is a word, it will be pushed as a literal.

This operation is efficient and does not copy the quotation.

Examples
USING: kernel prettyprint ; 5 [ . ] curry .

USING: kernel prettyprint see ; \ = [ see ] curry .
[ \ = see ]

USING: kernel math prettyprint sequences ; { 1 2 3 } 2 [ - ] curry map .
{ -1 0 1 }
