Re: [rules-users] Can I reuse eval output?

Hi,
I've learned the use of eval() is not efficient, but it cannot be avoided in
many cases.
However, using temporary variables I tried:
when
$tmp: eval(...)
($tmp == false) or (eval(...))
Then
...
end
The above doers not compile; is there an alternative to reduce the number of
evals by reusing their output?
no
Another question is, is tehre something wrong in the above definition
from a
declarative programming point of view?
its not idea - but sometimes over use of eval can't be helped - only you
know the answer to that, being your domain model expert.
Thanks,
Arjun
