commit 32702f847fb49da649f4362b0de3084890ac8129
Author: Richard Kreckel <kreckel at ginac.de>
Date:   Tue Nov 26 00:21:28 2024 +0100

    Avoid "expression with side effects..." warning using ex_to<T>().
    
    Clang++ warns that instantiations of this inline template function
    ex_to<T>(const ex &) are "expression with side effects [that] will be
    evaluated despite being used as an operand to 'typeid'".
    
    Let's declare this ex_to<T>() as a pure function (i.e. having no
    side effects) for compilers which support __attribute__((__pure__)).
    
    GCC seems to support this attribute since more than ten years.
