module Perl6::Plan::Design::Summer_2005

The current design calls for the following:

• A PGE-based parser converts Perl 6 source into a parse tree

• Semantic analysis - parse tree to Parrot Abstract Syntax Tree
• PAST structure generic
• Initially based on "Pugs Intermediate Language" (PIL)
• Design and build "tree transformation rules" system

• Synthesis - compile abstract tree to target environment
• Parrot Opcode Syntax Tree (POST) - low-level syntax tree
• Corresponds closely to operations available in environment
• Can go quickly from POST to bytecode

• Transformation tools designed to be reusable for other languages
