The name of the imported file as it appears in the Sass document.

Returns the resolved name of the imported file, as returned by \{Sass::Files#find_file_to_import}.
@return [String] The filename of the imported file.
This is an absolute path if the file is a `".sass"` or `".scss"` file.
@raise [Sass::SyntaxError] if `filename` ends in `".sass"` or `".scss"`
and no corresponding Sass file could be found.
