Syntax coloring is done in two steps:
1. colorize based on simple tokens, like keywords, string literals, etc.
2. colorize based on the semantic of names (functions, typedefs, etc.)

The second step requires building an AST (abstract syntax tree) from the
source and resolving the names to their "bindings", ie. their semantic
meaning. In the presence of syntax (or other) errors, this name
resolution may fail and therefore no coloring will be applied.
