Having the compiler lower string interpolation to some hidden template is - AST
macros. We're not doing AST macros.
Hidden user-defined semantics are not for D. Every language I'm familiar with
that supports it wound up with users creating their own completely undocumented
personal language that nobody else can use or has the remotest interest in using.
Exhibit A: https://www.boost.org/doc/libs/1_72_0/libs/preprocessor/doc/index.html
Everyone agrees, but says "but I know how to do AST macros in a sane way."
If someone sees an i"abc" in the source code, they should be able to look in the
language spec and know exactly what it does. They should not have to go trolling
through imports looking for the definition of some template they never heard of.
