I'm new to Scala... Here's the code: def ack2(m: BigInt, n: BigInt): BigInt = { val z = BigInt(0) (m,n) match { case (z,_) => n+1 case (_,z) => ack2(m-1,1) // Compiler says unreachable code on the paren of ack2( case _ => ack2(m-1, ack2(m, n-1)) // Compiler says unreachable code on the paren o...
Hi, I've seen the following code, taken from the libb64 project. I'm trying to understand what is the purpose of the while loop within the switch block - switch (state_in->step) { while (1) { case step_a: do { if (codechar == code_in+length_in) { st...

Is there a hint, such as through a pragma, or builtin that I can pass to GCC (or any other compilers for that matter), that will warn or error during compilation if it's ...
