Sadly that does not work. It should return false, rather than an error
message. Use of typeof seems OK.
julia> st = "these"
"these"
julia> st <: Number
ERROR: type: subtype: expected Type{T<:Top}, got ASCIIString
julia> typeof(st) <: Number
false

Check out issubtype:

And the corresponding operator (since it's use so much):
x = 1
x <: Real
true

typeof(var) gives something too specific, like Int16, Float32,
etc. Is there a convenient way to determine if var is a number or
something else (string)? I tried isreal(var), but it gives an
error in case var is not a number.
