> I was doing some benchmarks on a very tight loop, and I discovered that when a
branch is "curly" enclosed, then it prevents inlining:

It's far simpler then that - take a look at inline.c and observe that it only
ever inlines if/else that immediately containt return statement. Braces turn
return statement into a block hence destroying this hack.

What needs to be done is to IMPLEMENT inlining of if/else/switch/while
statements.
One general way to do that is to treat all statements as expressions (e.g.
yielding void) inside of the compiler.
