Complain about addr:housename matching addr:housenumber and differing solely by capitalization

[mkoniecz]

What steps will reproduce the problem? ¶

1. Create closed way
2. Add to it addr:housename=2D and addr:housenumber=2d
3. Run validator

What is the expected result? ¶

Validator complains that addr:housename and addr:housenumber are suspiciously similar.

What happens instead? ¶

Nothing. Note that in case of exact match validator complains already.

Please provide any additional information below. Attach a screenshot if possible. ¶

Hm. It seems the combination of "de-referencing" * and flags is not yet supported via mapcss. I tried

*[a][b][a =~ */(?i)b/] {
    throwWarning: tr("Same value of {0} and {1}", "{0.key}", "{1.key}");
    assertMatch: "node a=1 b=1";
    assertMatch: "node a=1a b=1A";
    assertNoMatch: "node a=1 b=2";
}

but JOSM throws a NPE.
