Qt for Python (PySide/Shiboken)

Hi! Does someone maybe know how to avoid normalizing of function arguments in shiboken6? I try to make a binding for function(constructor) with signature Query(const std::initializer_list<QPair<QString, QString>>& l). It transforms first QPair to std::pair and I get an error, because there is no constructor with signature Query(const std::initializer_list<std::pair<QString, QString>>& l) . I tried to avoid that by using <modify-argument>: <modify-argument index="1"> <replace-type modified-type="std::initializer_list&lt;QPair&lt;QString, QString&gt;&gt;" /> </modify-argument> Unfortunately it has no effect.
