Lambda/anonymous procedures

Lambda procedures are procedures that are functioning as arguments in instructions.

mov tlr, (proc)
	halt 234 ; return a value
(end)

Now tlr is set to 234.

Logic in lambdas

Warning

This feature was added in build 31.

Anonymous functions can have their own sealed labels within them, which means you can perform logical operations inside lambdas such as loop, callc, jmp and more.

.text
    thread thisisfun -> {
        mov tlr, "this is really fun"
        call std::ios::writeln
        mov tlr, 908
        call std::ios::writeln
        mov tlr, 243.4
        call std::ios::writeln

        mov tlr, (proc)
            int 0x3
            mov rax, 4
            mov tlr, "Hi from lambda in thread\n"
            mov fdx, 1
            sysenter "ios"
            syscall
            {:lmao}
            syscall
            loop rax, lmao
            int 0x3
            halt 0
        (end)
    }

As you can see, lambdas in threads have their own labels because the JIT compiler ignores the sealed labels within the (proc) block.

.text
	mov tlr, (proc)
		jmp label2
		{:label1}
		jmp label3
		{:label2}
		jmp label1
		{:label3}
		halt 0
	(end)
