Implementing the Pratt parser: Identifiers
The main idea behind the pratt parser is the association of token types with parsing functions. In the last session, the types for such functions were added. Today, the parser was extended to include prefix & infix function maps.
Identifiers
The simplest identifier in the monkey programming language is:
foobar;
So this was the starting point, and extended the parser to be able to parse this
expression. This required adding a parseExpressionStatement & parseExpression methods to the parser.
The parseExpression method took a priority, which is a enum of precedences amongst the operators in
the language. Although the precedence is not completely implemented, it is a good start to have it in place.
