The more interesting question is: how do you expect to
adress the var in the code that follows? I guess the compiler
won't have a problem with taking $::(calc_varname()) as
a variable name. The name doesn't appear anywhere outside the
scope anyway. But you should also not expect any &calc_varname
beeing called at runtime. And at most once during compile time.

Well, &my has got a runtime counterpart which creates a fresh
set of local variables everytime the code object is invoked.
