Re: [axiomengine-developers] AxiomCollection.cs design issue

[Michael C. <cum...@gm...>]

Why the restriction on having the has start with a letter? We are not
creating a c# variable, also special characters should be ok as well. This
is a value that is ( read should be ) only used internally in the engine (
since it's autogenerated. )

Anyone needing the key value for persistance would want to have their own
naming scheme and not rely on the engine to create a key for them. ( For
things like the DotScene format, or any other custom scene format ).

As for generating a hash, key.GetHashCode() should suffice.
