func:parseAst

parseAst(src)

Parse Axon source code into an abstract syntax tree modeled as a tree of dicts. Each node has a type tag which specified the node type. Common AST shapes:

123    =>  {type:"literal", val:123}
a      =>  {type:"var", name:"a"}
not a  =>  {type:"not", operand:{type:"var", name:"a"}}
a + b  =>  {type:"add", lhs:{type:"var", name:"a"}, rhs:{type:"var", name:"b"}}

NOTE: the keys and structure of the AST is subject to change over time.
