[julia-users] Is it possible to initialize a type parameter with promote_type()?

[Jeffrey Sarnoff]

is there a way to do accomplish this?

immutable Ivl{B<:AkoBound, R<:Real}  # R <-- 
promote_type(typeof(lo),typeof(hi))
    lo::Real                                               # allow lo, hi 
to differ in type (subtypes of Real)
    hi::Real
    ??    
end
