Re: [Objectscript-users] Embedding error. Assing value.

[Rob C. <ro...@ti...>]

Hi Sergio,

I think you end up with val being the value of foo, rather than the  
reference to foo.  So what ends up happening is something like "5 =  
101;".  Try this instead:

    a.lookupInScope("foo").opAssign(...)

What you are trying used to work long ago, but then I realized that  
it had the result that someone could do something like "someFxn() =  
3;", which could let the caller modify private members of an object  
accessed thru an accessor function, which isn't good.  I need to  
update the embedder's guide... it is a bit out of date in this respect.
