in reply to Strange Smart Match behavior

I haven't looked at your problem in detail, but I can tell you that the behavior of smart matching changed a lot between 5.10.0 and 5.10.1 (whereas it's relatively stable since 5.10.1).

Relying on the smart matching features of 5.10.0 thus isn't the best of ideas, comparable to building your house on sand.

A quick glance over the debug output implies that $mistery is the empty string, and thus numerically compares equal to '0'. But I could be wrong here.

    But then why would setting a variable to the explicity empty string fail to match, unless it was first compared to $mystery
