[julia-users] Is this a feature or bug?

[Lutfullah Tomak]

type T1
x::Int #It can be any type
end
Base.convert(::Type{T1}, x::Int)=T1(x)
a = T1[1:3;]
a' #--> gives error trying to convert T1 to Int.
b = T1[1:3;]
b[1] = a[1] #--> the same error
b[1] = T1(1) #--> No error

Somehow, right hand side is being converted to Int while assigning to left hand 
side from getindex.
Is this right behavior? On julia 0.4.2 windows 10 64bit.
