UndefVarError: T not defined

[MaximilianJHuber]

When I load a table that I saved with an old version of JuliaDB using master versions of JuliaDB, MemPool, IndexedTables and Julia 1.0.3:

UndefVarError: T not defined

Stacktrace:

Any ideas?

I found the offender:

function deserialize(io::AbstractSerializer, ::Type{MMWrap})
    MMWrap(mmread(T, io)) # gotta keep that wrapper on
end

I'm guessing it should be T::Type{MMWrap}? Looking into it now...

This is not fixed on master.
