Ummm, not quite. It'd be more like:
<!--- This doesn't work --->
<CFSET
StructInsert(struct,var,ListAppend(StructFind(struct,var),value),"true")>
<!--- Nor does this --->
<CFSET StructUpdate(struct,var,ListAppend(StructFind(struct,var),value))>
But, you can't do that because the StructFind() will fail if var is not
already a part of struct. Replacing StructFind() with an operator[] call
won't work, either, for the same reason.

Tres cool. :) I'd missed them, completely. Interesting how the
documentation says that they will return the keys in any order, but they are
always alphabetical (just as they have always been). Wonder what the deal
with that is?
At any rate, I guess I'll have to update my little function cheatsheet that
I have on my wall. Anyone got a one-page PDF of the functions and their
parameters that is up to date? I could make one, but if there is one
already out there, then I shan't bother.
Thanks,
Rick
