Activating the compiler

In fact, one can get the parse tree directly from the perl6 compiler:

.local pmc perl6, match
perl6 = compreg 'Perl6'                  ## get the compiler
match = perl6(code, 'target'=>'parse')   ## return a parse tree

Or from the command line:

parrot perl6.pbc --target=parse hello.p6

There are also --target=PAST, --target=POST, and --target=PIR options.
