Make the parser tree serializable with the \serialize() function.

Motivation

Making the parser tree takes most of the total computation time.
If I could "cache" it somehow, it would be great !

Example

$tree = $parser->program();
print(\serialize($tree));

yields

Serialization of 'Antlr\Antlr4\Runtime\Comparison\Equivalence@anonymous' is not allowed

Alternatives

• Make the grammar more efficient (there's room, I'm a noob)
• Use a visitor to transpile to target language (but code gen is always tricky)
• Make my own AST from the parser tree, and somehow ensure it is serializable (contexts?)
• How do YOU do it ?

Additional context

The vt time is the visitor. The rest could be cached, perhaps.
On more complex scripts, with nested flow statements, it goes up to seconds.
