We are trying to minimize the divergence. Thus the use of conditional tense and *mostly" word in the sentence "could mostly run on a CPU without a specific compiler", as a wishful thinking design trade-off, trying to minimize the rewriting a user has to do starting from a plain C++ function.

Probably we can discuss this next week off-line during a ISO C++ SG14 or SG1 session...
