[REBOL] Re: Apparent newbie question

Rebol is strict about left to right evaluation.
I remember Holger commenting about in-fix operators
(operators with two surrounding arguments)
that when you see an expression like this:
1 > 2
then you need to imagine that the ">" moves to the front:
> 1 2
(to be a prefix operator.)
Now it looks like any other function.
So in the expression:
length? test-block < 4
you should imagine this:
length? < test-block 4
Now rebol will evaluate like this:
length? (< test-block 4)
which leads to the error:
** Script Error: Expected one of: block! - not: integer!
Who expected it? The < operator, of course.
