Constructor doesn't fall back to convert?

[colinfang]

immutable AAA
    x::Int
end
Base.convert(::Type{AAA}, x::Float64) = AAA(1)
AAA(1.1)
# Inexact error

Seems there is another rule taking priority over the fallback.

Is this the desired behaviour? Do I have to manually build a constructor A(x::Float64) in this case?

I think this was covered as document issue a while ago. There is always one argument default constructor from Base definitions. So, you need A(x::Float64).
