[julia-users] function isabstract(::DataType)

[Stephen Chisholm]

Is there a way to check if a given DataType is an abstract type?  I've come 
up with a crude method below but thought there should be a better way.


function isabstract(t::DataType)
    try
        t()
    catch exception
        return (typeof(exception) == ErrorException &&
                string(exception.msg) == "type cannot be constructed")
    end
    return false
end


Cheers, Steve
