How to use quoted let bindings

How can I use a quoted let binding? Especially an identifier that is a keyword in Nix.

For instance, how would I use the assert identifier I’ve defined here:

let "assert" = 3; in ...

It is possible to inherit it to an attrset, but that seems somewhat hacky:

> let "assert" = 3; in { inherit "assert"; }."assert"

Is there an easier way to do this?
