SMOP Mold: Revision 9

(Mold is currently under implementation)
SMOP Mold is a register based interpreter implementation
A DSL called m0ld is used to represent mold opcodes in text form

A Mold block(?) is composed of three parts

* the number of registers used by the program (not counting the ones used to put constants or the 3 special ones)
* constants - which are put into registers
* opcodes

The registers 1,2,3 are initialised with

* interpreter
* identifier
* captures

Mold opcodes

# call invocant,identifier,named,positionals,target
# call2 responder,capture,target
# goto label - jumps to label
# br register,iftrue,iffalse - jumps to iftruel if the native bool in register is true to iffalse otherwise

$*OUT.print("hello world\n") be translated to something like

my $out;
my $OUT = "$*OUT";
my $print = "print";
my $curly = "postcircumfix:{ }";
my $SMOP__S1P__RootNamespace = $SMOP__S1P__RootNamespace;
my $hello_world = "hello world\n";
$out = $SMOP__S1P__RootNamespace.$curly($OUT);
$out.$print($hello_world);
