## Descripción desde docstring

Como las descripciones tienden a ser largas y cubrir múltiples líneas, puedes declarar la descripción de la *path operation* en la <abbr title="un string de múltiples líneas como la primera expresión dentro de una función (no asignada a ninguna variable) usada para documentación">docstring</abbr> de la función y **FastAPI** la leerá desde allí.

            final String[] lines = value.split("[\r\n]");
            for (final String line : lines) {
                if (StringUtil.isNotBlank(line)) {
                    final int pos = line.indexOf('=');
                    if (pos == 0) {
                        paramMap.put("unknown." + (unknownKey + 1), line.substring(pos + 1).trim());
                        unknownKey++;

    @Override
    public boolean hasNext() {
        if (line == EMPTY) {
            line = ReaderUtil.readLine(reader);
        }
        return line != null;
    }

    @Override
    public String next() {
        if (!hasNext()) {
            throw new NoSuchElementException();
        }
        final String result = line;
        line = EMPTY;
        return result;
    }

    @Override

	return data
}

// ScanLines is a split function for a [Scanner] that returns each line of
// text, stripped of any trailing end-of-line marker. The returned line may
// be empty. The end-of-line marker is one optional carriage return followed
// by one mandatory newline. In regular expression notation, it is `\r?\n`.
// The last non-empty line of input will be returned even if it has no
// newline.

Each file is a list of API features, one per line.

go1.txt (and similarly named files) are frozen once a version has been
shipped. Each file adds new lines but does not remove any.

except.txt lists features that may disappear without breaking true
compatibility.

Starting with go1.19.txt, each API feature line must end in "#nnnnn"
