Module hasproperty, getproperty Inconsistency

The easier part first. Here an example for the different ways to query namespaces and structures

# For modules

@show isdefined(Main, :sin)
@show isdefined(Main, :tin)

@show getproperty(Main, :sin)

# For structs

struct Example
    d
    Example() = new()
    Example(d) = new(d)
end

e = Example()

@show hasproperty(e, :d)
@show isdefined(e, :d)
# @show getproperty(e, :d) #fails

e = Example(42)

@show hasproperty(e, :d)
@show isdefined(e, :d)
@show getproperty(e, :d)

yielding

isdefined(Main, :sin) = true
isdefined(Main, :tin) = false
getproperty(Main, :sin) = sin
hasproperty(e, :d) = true
isdefined(e, :d) = false
hasproperty(e, :d) = true
isdefined(e, :d) = true  
getproperty(e, :d) = 42

For the second part:

I’ve got somewhat accustomed to it. Do you have a better idea?
