Parrot で eval もできる

Evaluating a Code String

.sub main
        .local pmc compiler, generated1, generated2
        .local string source1, source2
        compiler = compreg "PIR"
        source1 = ".sub foo\n$S1 = 'in eval 1'\nsay $S1\n.end"
        source2 = ".sub foo\n$S1 = 'in eval 2'\nsay $S1\n.end"
        generated1 = compiler(source1)
        generated2 = compiler(source2)
        generated1()            # in eval 1
        generated2()            # in eval 2
        foo()                   # in eval 2
        $P1 = generated1
        $P1()                   # in eval 1
.end

Parrot はとことん言語実装のための VM だな。
