Slide 3: Cross Compiler
- The NQP and Rakudo compilers are also cross-compilers by this definition,
  since their output works on any platform

Slide 9: sysroot
- So if I follow, this is only relevant to compiling native code, and it says
  where the headers etc. for that target platform live?

Slide 14:
- The MoarVM build process builds itself a minilua as a build tool. If I

1. Should two different taps of a a serial supply be run simultaneuosly?

$ perl6 -e 'my $p = Supplier.new; my $s = $p.Supply; $s.serial.say; $s.tap({ sleep 1; "42 {now}".say; }); $s.tap({ sleep 1; "43 {now}".say }); $p.emit(42); sleep 3;' True 42 Instant:1449454902.847377 43 Instant:1449454903.854135

No. Supplies do not introduce concurrency, at least not unless you explicitly ask for it with something like the start method. So the emit here is doing no more than a loop through the taps, calling the closures passed to tap one
