Yes if we construct the struct with an integer. There are some
stylistic choices to be made.
The first choice is: do we use this (I seem to recall being
told in Java with classes there is debate whether 'this' is
preferrable or not).
this(int y)
{
//choice 1:
this.a = this.INT_C.Yes;
//choice 2:
a = INT_C.Yes;
}
The second choice is: do we qualify by the struct name:
this(int y)
{
//option 1
a = Foo.INT_C.Yes;
//option 2
a = INT_C.Yes;
}
The reason I ask, is that I remember some cases in Java where
it was advantageous to use 'this'.
There is no need to qualify by either of them.
If you do want to qualify for readability reasons then "this"
would be preferable in my opinion as it will remain correct if
you later change Foo to a templated struct.
