Are these the only possibly assignments? Isn't it possible to do:
set my_foo=$my_bar
or
set status_format="-%r-Mutt: %f...%>-(%P)-$timeout--"

I would say that:
* User-defined variables have type string.
* The value part of a set command is a string and variables are
expanded as strings.
* In an assignment to a built-in variable, the value is parsed
according to the type of the variable. If the string
representation is invalid, an error message is displayed.
