why when I use std::left in an interterpreted script I got this:
------------> LOADING LIBS <------------
loading 0x2acceb18cd30 libHist[OK]
loading 0x2acceb18cd30 libPhysics[OK]
loading 0x2acceb18cd30 libXMLParser[OK]
loading 0x2acceb18cd30 libbase_selectors[OK]
loading 0x2acceb18cd30 libcalibration_utils[OK]
------------> LOADING LIBS <------------
as you can see std::left is printed as address and has no effect
