Comment(by kristian):

 Hmm, right.

 This requires some thought, we're discussing it at the moment.

 The problem is:

 {{{
 if (!foo ~ "bar")
 }}}
 used to mean the same thing as:
 {{{
 if (!(foo ~ "bar"))
 }}}

 However, that is counter to what many would expect from typical operator
 precedence, and it might be "more correct" to have it mean:

 {{{
 if ((!foo) ~ "bar")
 }}}

 Which, in turn, doesn't really make sense to write at all.

 I'll drop a mail to the -dev list and see what happens.
