Does a Control Exist?

[Ray]

After loosely following the item delimiter thread last week a similar 
idea came to me today which might be an interesting discussion.

It's often time consuming to type spell out...
    if there is a field "My Field" then put field "My Field" into myVar

If I don't first check to see if the control exists [and it doesn't] I 
get an error and the script stops execution.

I don't have to do this with a custom property.  That is if the script is...
    put the NewProperty of this card into myVar
and said property doesn't exist, I simply end up with nothing in myVar, 
but it doesn't cause an error and the script continues.

Does anybody think it would be worth it to have a way to stop errors 
from being produced when referring to non-existent controls?
