In a test case I have reduced to a struct that uses a static this

nothing accept internal things.

yeah, at an AST level it makes sense why it was implemented like

it's unfortunate that there's no straightforward way to express

For anyone still interested in this problem: Steve's pull request fixing the
problem is included in D 2.081.0.
I can experiment as soon as DMD 2.081.0 is released but will have to wait till
the fixes get into LDC to create production code.
Moral of the story: silent, except during gdb debugging,

In the code I posted before about CRC, sometimes I get a

filter those out using traits. Is there any way to determine if a
module is visible/reachable in the current scope?
