These could use some documenting (and yes, I know the answer to many) for

good thing)
*) How do I declare an externally visible subroutine?

*) How do I store a global variable

*) How do I load a global variable

*) How do I call an external function

*) How do I get the sub pmc for a sub declared later (or earlier) in the
file?
*) How do I (or even can I) have a file-scoped variable? (like .local,
only for all code in the file)


*) How do I do the following in PIR:

package Foo::Bar;

my $joe = 42;

sub new {
        bless {};
}
sub prnJoe {
        my $self = shift;
        print $self->jo;
}
package main;

$f = Foo::Bar->new();
$f->prnJoe();
Would also be *really* great (I'm trying to implement the IMC codegen in 
PHP for classes and objects right now :)
