O que costuma-se supor

transformFromAstSync modifies the provided AST object in place during traversal and populates result.ast with the transformed tree.

O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.

Contrato

• transformFromAstSync preserves the input AST node unmodified and sets result.ast to null unless cloneInputAst is set to false and ast is set to true.
• inputAst.program.body[0].kind remains 'let' when cloneInputAst defaults to true
• defaultResult.ast is strictly null on default invocations
• cloneInputAst: false mutates the passed AST in place, changing kind to 'const'
• explicitResult.ast returns the root File AST node only when options.ast is explicitly true
