<![CDATA[An one liner to unpack QRegularExpressionMatch results into multiple variable?]]>I have a QRegularExpression object that captures multiple groups from strings, and a QRegularExpressionMatch::capture(n) to split them out individually.

Is there an one liner like in python where I can unpack them all at once like this instead of one at a time?

[id, name, type, text] = infoREMatch.capture();

Scroll to the tuple example. Yes Python has some nice things. I would really love comprehensions in C++.

But still it couldn't be unpack.

? In C++ it's like a one-line function wrapper. Yes, C++ isn't the same as Python. Thank goodness! Use Python + PySide2/PyQt5 if you prefer what you can do there over C++.

I was using this one now, it's a little bit better in mass control like trimming all elements at once. But still it couldn't be unpack.

The closest is QStringList QRegularExpressionMatch::capturedTexts() const.

No, there is not
