mao-yining created an issue (vim/vim#19484)

Steps to reproduce

The following code works as expected:

vim9script
printf( # comment
    'sdfl'
)

But this similar code inside a lambda fails:

vim9script
const a = () => {
    printf( # comment
        'sdfl'
    )
}

Error: The comment # comment is not properly ignored when inside a block context, causing a syntax error.

Expected behaviour

Expected behavior: Comments should be ignored consistently regardless of context.

Version of Vim

9.2.0043

Environment

MS-Windows
