Function documentation

ExpressionSyntax& slang::Parser::parseExpression()

Parse an expression / statement / module / class / name. These are mostly for testing; only use if you know that the source stream is currently looking at one of these.

SyntaxNode& slang::Parser::parseGuess()

Generalized node parse function that tries to figure out what we're looking at and parse that specifically. A normal batch compile won't call this, since in a well formed program every file is a compilation unit, but for snippets of code this can be convenient.
