sure there is no way to check. this 'final try' helper is required
exactly 'cause compiler can't do necessary checks, and programmer can
assure compiler that "it's ok, we'll catching 'em all here!" this way
'try/catch' will not be "nothrow", only 'final try/catch'. and there
will be *nothing* that can be catched outside of 'final try/catch'.
i.e. if something was not catched in 'final', it's a fatal bug.
crash-boom-band, we are dead.

but i don't want to create ER, 'cause it will be rejected. it implies
code breaking ("simple" try/catch can't be used in 'nothrow' functions
anymore), and ERs with code breaking feature have no chances.
