I use `pragma(inline, true)` all over my code. And by default, DMD inlines these functions even in debug builds, which normally is great.
What sucks about this is that stepping through the code in a debugger is way worse because the the "step-over" operation no longer works properly when trying to step over an inlined function call. Maybe this is a bug in the PDB output, but what happens is the inlined function call still takes you into the inlined function body as if you were using step-in. step-over essentially becomes useless for these function calls.
Please add a flag
-inline=false
to hard disable all inlining in the compiler.

Given the history of dismissing the addition of CLI options, I think that this bug report has a small chance of being fixed. However, as a workaround you could define an `enum INLINE=true` and use `pragma(inline, INLINE)` instead of `pragma(inline, true)`. That way, you can just switch the INLINE to false when you don't want the compiler to do any inlining.

This doesn't work for inlined functions in dub packages, as you have no control over the source in that case. An actual work-around here is using ldc and passing in --enable-inlining=false, which really sucks because the ldc build for my project is way slower.
Since there's already a precedent from LDC, this seems like a really sensible addition. It seems like a smaller change that would make using debuggers a much better experience for everyone. Although, I'm starting to wonder how many D developers use debuggers at all.
