While DMD still doesn't inline functions that (directly) contain a "throw"
statement, the original poster's issues with std.range and emplace have largely
been addressed several versions ago (at least as far back as 2.060, maybe
more):

- Many uses of enforce in std.range, such as the ones in Take, have been
replaced by asserts.

- Functions like Take.popFront() and Take.front() are inlined (likely due to
the switch to assert).

- Some of the enforce functions (except for errnoEnforce and the enforce that
takes a lazy Throwable as a param) are inlineable because they don't use
"throw" directly. Instead, they call the private helper "bailOut" which does
the actual throwing. The "bailOut" function isn't inlineable, but that
shouldn't be a problem since it only gets called when the condition fails.
