yes, it's supposed to do so. IIRC it's been discussed time ago, that it'd be
ugly, uncomfortable, unexpected to be required to escape math symbols within
:@:...:, only because they happen to be our delimiters.

There might be other cases where we'd require the parser to be smart enough
to not put too much burden on user's fingers, but this is one I recall.

Note that

$  syscall () () () /\/path\/to\/exec args/

is likely not such case, since path delimiter happens to match our delim on
some OS but not others, so it's not a well defined situation.
