// Input
export const version: string;

// Prettier 3.6.0 (--parser=babel-ts)
SyntaxError: Unexpected token (1:21)

Miscellaneous: Avoid closing files multiple times (#​17665 by @​43081j)

When reading a file to infer the interpreter from a shebang, we use the
n-readlines library to read the first line in order to get the shebang.

This library closes files when it reaches EOF, and we later try close the same
files again. We now close files only if n-readlines did not already close
them.
