What should the new method be, precisely? I tried colon(start::JDate,
step::Real, stop::JDate) = JDate(colon(float64(start),step,float64(stop)) (I
have conversion rules defined for the JDate to Float64 conversions), but I
get several warning messages of the form:
Warning: New definition
colon(JDate,Real,JDate) at <path>\types.jl:25
is ambiguous with:
colon(T<:FloatingPoint,T<:FloatingPoint,T<:FloatingPoint) at
range.jl:122.
To fix, define
colon(JDate,JDate,JDate)
before the new definition.
Then, when I test this, I still get a Array{Float64,1}.
Thanks,
Chris
