I recently saw the following in the codebase:
bool bRes = (a < b) ? a=b, true : false;
If a < b, then a=b is executed and bRes is true.
What exactly is going on here? The docs for conditional operator don't mention anything about chaining expressions.
edit: to be clear I get the conditional operator part, it's the a=b, true as a single expression that confused me.
