How Should `TAKE []` React? Null? Error?

Early Ren-C introduced TAKE* as distinct from TAKE...

Experiments at being prescriptive worried that getting back a NULL might not be enough to warn you about a misunderstanding. So we wound up with this:

ren-c>> take []
** Error: TAKE-ing from an empty block, use TAKE*

ren-c>> take* []
; null

I think that this is a good example of something that fits in well with TRY, under the new definitional-error-powered conception:

>> block: []

>> take block
** Error: TAKE-ing from an empty block, if intentional use TRY TAKE

>> try take block
; null
