[REBOL] REBOL Enhancement Proposals (REPs)
From: geza67::freestart::hu at: 26-Sep-2001 0:00
Hello REBOLers,
Why wouldn't we collect - following the path of Python Enhancement
Proposals i.e. PEPs - REBOL Enhancement Proposals (REPs) ?
Some of us certainly sent ideas to RT's feedback but why couldn't we
share and discuss these information before transmitting it to RT's "magic
cauldron" ?
Let me start the row with my 2 (really two :-) ) cents :
REBOL Enhancement Proposals
===========================
#1 Immediate (paren) values in paths
It would be a very nice and elegant construct
if paths may contain immediately evaluated paren expressions yielding
path fragments, not only words:
e.g.
a: [1 2 3]
and instead of:
b: 2
probe a/:b
this:
probe a/(1 + 1)
or with a twist:
probe a/(b)
I think that this modification is not simply a syntactic sugar but eliminates
setting intermediate working words and using them only once -
i.e. in the creation of a dynamic path value.
#2 "Polymorph" multiple 'SET
SET now expects a word to set. Words in objects seem to be buried deep,
being not really suitable for an elegant multiple set operation:
e.g.
a: context [ b: context [c: none]]
d: context [ e: none]
The logical and straightforward way unfortunately does not work:
set [a/b/c d/e] [1 2]
The current method to bind a word in an object to a value is IMHO awkward and
distorts code readability thus expressiveness:
set reduce [(in a/b 'c) (in d 'e)] [1 2]
