* Implemented by nodes that implicitly coerce one or more of their child

|
* nodes to string at runtime (PHP string casts, regex matching, comparisons,
|
|
* range bounds, template-name resolution by the loader, etc.).
|
|
*
|
|
* The sandbox node visitor wraps the listed children with a CheckToStringNode
|
|
* so that an implicit `__toString()` call goes through the sandbox policy
|
|
* check, independently of where this node's result is used.
|
|
*
|
|
* This is distinct from {@see OperatorEscapeInterface}, which describes
|
|
* operands whose value becomes this expression's value (passthrough operators
|
|
* like ternaries) and is consumed by the escaper.
