Hi Mirek,

Looking forward to the release...

Meanwhile, can you take a look at the MSC compilation (MSBT22x64 in my case):

C:\upp-git\upp.src\uppsrc\Core\Topt.h(168): error C7525: inline variables require at least '/std:c++17'
C:\upp-git\upp.src\uppsrc\Core\Topt.h(172): error C7525: inline variables require at least '/std:c++17'
C:\upp-git\upp.src\uppsrc\Core\Tuple.h(170): error C7525: inline variables require at least '/std:c++17'
C:\upp-git\upp.src\uppsrc\Core\Tuple.h(174): error C7525: inline variables require at least '/std:c++17'
C:\upp-git\upp.src\uppsrc\Core\Tuple.h(179): error C7525: inline variables require at least '/std:c++17'
C:\upp-git\upp.src\uppsrc\Core\Complex.h(58): error C7525: inline variables require at least '/std:c++17'

EDIT: Adding '/std:c++17' to Common options in build methods for MSC helped here.

Best regards,

Tom
