3rdparty/stout/include/stout/strings.hpp
Lines 390-392 (patched)

    This is definitely simple but is this how C++20 std libraries implement 
this?
    
    It seems non-optimal to always have to scan the entire prefix array for the 
null character? E.g. startsWith("foo", "bar ... <1MB>"). Ideally this could 
trip to false after checking the first character only?
