[REBOL] Re: The evaluation semantics
From: behrangsa:g:mail at: 5-Sep-2005 10:49
Hi all,
Thanks for all the responses. The main reason I asked this question is
that in the REBOL document it's written that "In REBOL there are no
special operator precedence rules for evaluating blocks" and as said
earlier "The values and words of a block are always evaluated from
first to last..."
But it turns out that this is not true all the time (or am I still
missing something?)
So I thought it would be better to update these portions of the document.
