Hmm, not very good solution. In C++ you can not to write type 
and compiler will deduce it automatically. In D, as I 
understand, this feature isn't supported.

Yes, D's syntax for structure literals requires you to write the 
name of the type:

https://dlang.org/spec/struct.html#struct-literal

If the name of the type is too cumbersome to write out, you can 
use an alias:

alias ShortName = MyLongAndComplicatedType!(PossiblyWith, 
TemplateArguments);
foo(ShortName(a, text));
