Recently I discovered a strange bug in dmd -cov, that I finally got some
time today to reduce to a smallish test case. However, I can't seem to
get rid of the dependency on std.stdio; anybody has any idea how to
reduce this code further?

This is a very strange bug where decreasing code coverage actually
increases the reported coverage percentage. :-P

Sorry, not helping but rambling below...
Yep, not surprising that conditional expression has such issues. The
last time I checked Python code for coverage, they were missing
uncovered branch of the conditional expression.
[And saying this without testing.] Additionally, what about lazily
evaluated sub-expressions like function arguments? So, per-line coverage
is not sufficient anyway.
