Subtypes of an abstract type

General Usage
1

Hi,

Is there a function which takes an argument and returns a list of that argument’s subtypes.

Example:

abstract X

type Y <:X
end

type Z <:X
end

get_subtypes(X) will return [:Y,:Z]

Thanks

Also remember you have apropos

julia> @doc apropos
  apropos(string)

  Search through all documentation for a string, ignoring case.
