/**
* An annotation on methods that requests that the compiler should try especially hard to inline the
* annotated method. The annotation can be used at definition site or at callsite.
*
* {{{
* @inline final def f1(x: Int) = x
* @noinline final def f2(x: Int) = x
* final def f3(x: Int) = x
*
* def t1 = f1(1) // inlined if possible
* def t2 = f2(1) // not inlined
* def t3 = f3(1) // may be inlined (heuristics)
* def t4 = f1(1): @noinline // not inlined (override at callsite)
* def t5 = f2(1): @inline // not inlined (cannot override the @noinline at f2's definition)
* def t6 = f3(1): @inline // inlined if possible
* def t7 = f3(1): @noinline // not inlined
* }
* }}}
*
* Note: parentheses are required when annotating a callsite withing a larger expression.
*
* {{{
* def t1 = f1(1) + f1(1): @noinline // equivalent to (f1(1) + f1(1)): @noinline
* def t2 = f1(1) + (f1(1): @noinline) // the second call to f1 is not inlined
