Updated State of the Lambda

[William Clark]

One thing I've always wanted to point out concerning capturing mutable 
local variables that always seems to go unmentioned; it doesn't just 
risk race conditions, it introduces are whole new class of error:

void foo() {
     bar().run();
}

Runnable bar() {
     int n = 0;
     return () -> { n = 5; }
}

You don't have to just prevent them from leaving their capturing thread, 
you can't let them escape their capturing method as a return value or 
argument... Making them essentially useless.
