Paths are a series of values - each value in the series having a datatype.
So is a/5..10 one path of length two - the second value (5..10) being a new
datatype? Something like a pair?
But if it is a new datatype we would want to store them in a block
a: [1..3 5..10]
a/5..10 ...oh oh.
Or is a/5..10 meaning that .. is an operator with the necessary whitespace
missing in which case it should be written
a/5 .. 10
or perhaps even
.. a/5 10
Hmm...
I don't doubt that REBOL can be improved, but I've don't think I've seen any
compelling suggestion on this thread yet - though I do admit, lots of
innovation! :^)
Then again, I still occasionally lament the removal of aggressively
evaluated paths so who am I to comment?! (-:
