I'd like to see set-word! values require at least one white-space character
after the colon. Like this 'parse rule fragment:
Set-Word: [Word #":" some White-Space]
Where "Word" refers to the rule for the Word rule. Naturally, the reverse
should apply for Get-Word values, in this 'parse rule fragment:
Get-Word: [some White-Space #":" Word]
If Rebol 'loaded script and used 'parse like:
>> parse "x: :print b: test/:i: 4 [ foo bar ]" ""
== ["x:" ":print" "b:" "test/:i:" "4" "[" "foo" "bar" "]"]
Then the whitespace is automatically eliminated, and so can be eliminated
from the rules, giving these rules:
Set-Word: [Word #":"]
Get-Word: [#":" Word]
Then the path and set-path rule could be like this:
Path: [Word some [#"/" [Get-Word | Word]]]
Set-Path: [Path #":"]
Just some thoughts.
