OK, I didn't realize that. Even if I had studied all the order of

somewhat different than in most languages.
The initializer needs to go =inside= the
signature. I think you meant to write
(my int8 ($x, $y)) «=« 127;
It should already parse that way. scope_declarator is a noun,
and nouns may be used on the left side of an infix operator. When
scope_declarator sees something it doesn't recognize, it just stops,
so EXPR picks it up.
Now, it could be argued that it *should* be considered part of the 'my',
though in the case of 'my' it makes no difference. It could make a
difference for, say, 'state', though.
I can imagine people who don't know that they are working with a
signature object will write something like that, expect it to work, and
have it become real assignment rather than pseudo-assignment keyed to
the proper lifetime.
Using a declarator other than 'my' as part of a larger expression should
generate a warning. Or maybe just on the ones that might be mistakes,
such as involvement of assignment and lack of the actual initializer.
