Re: [Rails-devel] 1825 half-tiles

[Erik V. <eri...@xs...>]

The "existing mechanism" only allows opening hex edges that would otherwise
be closed, not the other way around.
Of course we can extend (or replace) that mechanism.  I'm just trying to
find out if this very minor issue (as JDG correctly points out) is really
worth it to create an exception for, also in the light of the uncertainty
about what the rules (as cited) really say.

BTW: Q11 is Crewe, not Wolverton.
