[REBOL] RFC: new feature for local word handling
From: robert::muench::robertmuench::de at: 31-Dec-2002 11:39
Hi, playing around with the problem to use a block of code that should
be executed in an other context but still uses local words I want to
propose a new feature.
IMO this problem comes up quite often, especially if want to use the
dynamics of Rebol for application architecture. Through the very dynamic
of Rebol it's mostly unpossible to handle the requirement with own
written code. IMO the only place to handle this with all respects to
dynamic execution is the interpreter itself.
How about this:
myblock: [
myvar: 3
print myvar * 3
myvar2: in system myvar
myvar2: myvar * 3
]
do/local myblock
This would define 'myvar and 'myvar2 to be bound to a local context.
'myvar2 will refer to the global word 'myvar and alter this. So when
using this you have to bring in the global words. But this is a lot
easier, because most of the time you know which global words are
available.
What do you think? Robert
