In C and C++, `inline` is a suggestion to the compiler that it 
should consider using [inline expansion][1] for calls to a 
particular function. However, the compiler is free to ignore this 
suggestion, and is also free to use inline expansion for 
functions that are not marked with `inline`.

In D, the closest equivalent is [`pragma(inline)`][2], which can 
be used to enable or disable inline expansion for a particular 
function. With `pragma(inline, true)`, the function will *always* 
be expanded inline; with `pragma(inline, false)`, it will *never* 
be expanded.
