[Series-announce] 2.1.4 released

[Fernando D. M. M. <mat...@in...>]

Optimization of expressions of the form (collect [type] (scan [type]
<list construction expression>

It only checks for QUOTE, LIST, CONS, COPY-LIST right now. The rest is
trivial to add [someone should
extend DECLAIM and PROCLAIM and add proper handling of FTYPE].

If it was not stated before, now it is:
COLLECT IS NOT REQUIRED TO CONSTRUCT new SEQUENCES.
It is guaranteed to do it in the cases where construction cannot be
opmized out,
for example: (collect (scan #(1 2 3))) (collect (scan-range :from 0
:upto 10)), or even
things like (collect (map-fn 'class #'class-of (scan
(class-direct-superclasses (find-class "FOO")))))
