Dear All,
How does one use 'alias' to incorporate function arguments as
well?
(I believe this is possible, from some of the examples of
aliasSeq, and
the traits.Parameters documentation. However, I was unable to
come up
with anything that works.)
What should replace the question marks (???) below?
>double bar( int a, double x){
> return a*x:
>}
>template foo(T){
> static if ( is(T==int) ){
> alias ??? = ???
> }
> else{
> alias ??? = ???
> }
>}
>
>// when T == int, I desire the aliasing to produce resulting
>code:
>foo( int a) = bar( int a, 42.33);
>
>// when T == double, I desire:
>foo( double x) = bar( 7, x);
Thanks kindly for any information!

PS I am aware of the "struct holding a function allowing multiple
dispatch concept"
... while that would fit quite okay here in my simple example, it
isn't appropriate
for my real use.
