it is possible

look for `AliasSeq`
in `std.meta`

foreach(T; AliasSeq!(float, double))

Stefan,

Thanks very much for your help here ... I had not
understood that AliasSeq worked in this manner.

I definitely need read the AliasSeq and try to understand
how to use this.

Best Regards,

Good Evening/Day,

Suppose I have a number of function templates that each take
two types, say S and T.

I would like to exercise my routines over the combinations
of types:

set of all S:  ( double[], float[], Complex!double[], 
Complex!float[])

set of all T:  ( double, float)

Is something along the line of the following sketch possible?

foreach( s in S){
   foreach( t in T){

  foo!(S,T)( T x, S y);
  biz!(S,T)( T x, S y);

   }
}

I have done some searching for hints about this, but I perhaps
my search terms are not very good.

All hint and pointers thankfully received.

Best Regards,
James
