I don't believe that it's legal to use a cast in an alias

that's certainly what the error seems to be indicating. Also,
using ref in a
cast is definitely illegal regardless of where the cast is. ref
is not part
of a type. The only places that you can use it are function
parameters, return
types, and foreach variables. If you want to do anything like
you seem to be
trying to do, you're going to have to alias a function which
does the cast for
you rather than try and alias the variable itself.
I also don't see anything here that would work as any kind of
multiple alias
this.

Thank you, I was assuming D worked as C++ but ref not being part
of type is so much better ! (According to Marc Schütz your
solution isn't doing so well.)
About alias working with identifier but not with (runtime)
expression. Alias should work with compile time expression like
map!(x=>2*x) right ? So a static cast should work isn't it ?
(though static_cast doesn't exist in D :/)
