FunctionDeclSyntax does not expand body

[zzyptr]

Description

FunctionDeclSyntax does not expand body as expected.

let functionDeclaration = FunctionDeclSyntax(
    name: .identifier("foo"),
    signature: FunctionSignatureSyntax(parameterClause: FunctionParameterClauseSyntax(parameters: [])),
    body: CodeBlockSyntax(statements: [])
)

will expand to

func foo() 

no body

I was unable to reproduce the issue.

let functionDeclaration = FunctionDeclSyntax(
  name: .identifier("foo"),
  signature: FunctionSignatureSyntax(parameterClause: FunctionParameterClauseSyntax(parameters: [])),
  body: CodeBlockSyntax(statements: [])
)
print(functionDeclaration.formatted())

prints

func foo() {
}

Which contains a body.

Are you doing anything differently? If so, can you share a reproducing project?

I am sorry. I found the body of the function was removed by a body macro that with a implementation of return []
