[REBOL] why 2 error?
From: pat665:ifrance at: 22-Nov-2001 22:30
Hi,
Reading Ladislav "Words, Aliases, Contexts, Visualizations, Bindings and
Scope in Rebol.html" I found the following function.
undefined?: func [
{determines, if a word is undefined}
word [any-word!]
] [
error? try [error? get/any :word]
]
I can't figure out why there is two error? in the last line.
It seems to me (and I have experimented on the console) that >> error? try
[get/any :word] << will do the job as well. I'm afraid I am missing
something because I have seen in many rebol-list posts that Ladislav is
dedicated to produce clean and concise code.
So what's wrong with my shorter (and presumptuous) version ?
Mais c'est en forgeant, qu'on devient forgeron, comme on dit chez nous.
