Inline functions [language.inline]

Avoid using explicit {.inline.} functions.

Pros

• Sometimes give performance advantages

Cons

• Adds clutter to function definitions
• Larger code size, longer compile times
• Prevent certain LTO optimizations

Practical notes

• {.inline.} does not inline code - rather it copies the function definition into every C module making it available for the C compiler to inline
• Compilers can use contextual information to balance inlining
• LTO achieves a similar end result without the cons
