You need to use simple variable assignments (:=) instead of recursive
assignments (=), so that the right-hand side of the assignment is
evaluated immediately when the variable is declared.

Otherwise, it won't be evaluated until the variable is used (and it will
be evaluated _every time_ the variable is used), which is definitely not
what you want.
