Structural pattern matching on expression tree

Checks if this Expr matches the given operator and operand patterns. Use null to match any value, or a specific value to match exactly.

Examples: $expr->matches('/') // is this a division? $expr->matches('/', 1, 2) // is this 1/2? $expr->matches('/', null, 2) // is this ?/2 (anything divided by 2)? $expr->matches('**', null, fn($e) => $e->matches('/', 1, 2)) // x^(1/2)?
