+// This is a pretty horrible hack to allow us to conditionally mark
+// some functions as 'const', without requiring users of this macro
+// to care about the "const-extern-fn" feature.
+//
+// When 'const-extern-fn' is enabled, we emit the captured 'const' keyword
+// in the expanded function.
+//
+// When 'const-extern-fn' is disabled, we always emit a plain 'pub unsafe extern fn'.
+// Note that the expression matched by the macro is exactly the same - this allows
+// users of this macro to work whether or not 'const-extern-fn' is enabled
+//
+// Unfortunately, we need to duplicate most of this macro between the 'cfg_if' blocks.
+// This is because 'const unsafe extern fn' won't even parse on older compilers,
+// so we need to avoid emitting it at all of 'const-extern-fn'.
+//
+// Specifically, moving the 'cfg_if' into the macro body will *not* work.
+// Doing so would cause the '#[cfg(feature = "const-extern-fn")]' to be emiited
+// into user code. The 'cfg' gate will not stop Rust from trying to parse the
+// 'pub const unsafe extern fn', so users would get a compiler error even when
+// the 'const-extern-fn' feature is disabled
+//
+// Note that users of this macro need to place 'const' in a weird position
+// (after the closing ')' for the arguments, but before the return type).
+// This was the only way I could satisfy the following two requirements:
+// 1. Avoid ambuguity errors from 'macro_rules!' (which happen when writing '$foo:ident fn'
+// 2. Allow users of this macro to mix 'pub fn foo' and 'pub const fn bar' within the same
