If I declare something as pragma( inline, true ) and it is 
declared public and then imported into another module will it 
then inline into the call site in GDC / LDC ? (Like a C function 
(or macro) whose body is given in whole in a .h file and 
force-inlined, not a call resolved by the linker.)

So that’s my question: does the import mechanism defeat enforced 
inlining in GDC / LDC?

Not the absolute end of the world if it doesn’t but then users 
will just absolutely have to cut and past the inline-critical 
code into their calling module. And it will be incredibly short 
code,  anyway in such a case, otherwise a call to a single copy 
of a somewhat longer routine might well be better if called from 
several places because of code-caching hotness.

I can’t test that yet myself as I don’t have a suitable test bed 
due to poor health - long story. I’ve been using godbolt.org 
Compiler Explorer to examine code generation quality.
