When a verb is !d, any built-in function call or primitive MOO expression that
raises an error simply returns that error as the value of the expression.
That's what happened here; as someone later pointed out, in a !d verb
	raise(X)
is equivalent to
	X
so your example is equivalent to
	`E_PERM ! E_PERM => E_INVARG'
which is clearly equivalent to
	E_PERM
(since the simple literal expression (E_PERM) can't raise an error).

There isn't any purpose in using either `...' or try...except...endtry in a !d
verb.  You should figure out why the verb used to be !d, fix those specific
expressions or statements using `...' or try...except...endtry, and then make
the verb +d again, working toward the proper goal of the elimination of all !d
verbs.
