Note that for some cases, security aware programs (CGI, daemons), you have
to be a bit more careful. A known dangerous case is stuff like
forcedirectories on directory hierarchies where you don't have read
permissions (but you do have "x" permissions) on all levels.

Fashion, not function. .NET has everything organized in static classes, and
embacadero wants to look more modern.

I wouldn't call this higher level. It is the same level just in OOP style.
