need simple examples of using QAST inside nqp programs

[tbrowder]

Problem

Use of QAST inside nqp code may sometimes be necessary such as in rakudu/src/Perl6/Pod.nqp,
and simple examples are needed for new developers.

Solution

I would like to see simple, runnable nqp programs that:

• create various QAST blocks defining objects such as a string, a list, and a hash
• use the QAST objects
• determine the type of an unknown nqp or QAST object
• show dumping an nqp object into QAST
