Why pragma?
Answered in another post.
Also how exactly it is supposed to work:
T func(args)
{
...
pragma(inline, true);
...
}
How to return to normal state then?
Not necessary when it's inside a function.
I'd strongly favor introducing a compiler-hint family of UDAs
and
force_inline/force_notinline as first among many.
I don't see an advantage of that over pragma. It also seems
like something that should be inside a function, not outside.
(After all, a function with no body cannot be inlined.)
Thanks for the code example. That helped me better understand
what is being proposed.
I like the idea of using pragma since it is built specifically
for the purpose of sending information to the compiler from code.
Also, I like not having to add another keyword to a function
definition. Especially since I already have "@safe pure nothrow"
in as many places as possible, for inline-able functions I'd
prefer to not have to add "inline" to that list. Using a pragma
would mean it could be implemented right away without worrying
about breaking any existing code. The proposal also satisfies the
needs of both parties. Especially since D is a flexible language
it would be nice to give such ability to customize code
generation to the programmer.
Given the above I think this is a good idea.
