Generate Python code objects by "assembling" bytecode
Description
peak.util.assembler is a simple bytecode assembler module that handles most
low-level bytecode generation details like jump offsets, stack size tracking,
line number table generation, constant and variable name index tracking, etc.
That way, you can focus your attention on the desired semantics of your
bytecode instead of on these mechanical issues.
In addition to a low-level opcode-oriented API for directly generating specific
Python bytecodes, this module also offers an extensible mini-AST framework for
generating code from high-level specifications. This framework does most of
the work needed to transform tree-like structures into linear bytecode
instructions, and includes the ability to do compile-time constant folding.
