Good way to organize constants?

[FANG Colin]

Say, I have a few constants

const VTYPE_BINARY = 'B'

const VTYPE_INTEGER = 'I'

const VTYPE_CONTINUOUS = 'C'

What's a good way to have a namespace on it?

So that I can use Vtype.BINARY, Vtype.INTEGER, Vtype.CONTINUOUS

Should I put those in a separator module? or create a type and get an instance of it?

module Vtype

    const ....

end

immutable Vtype

    BINARY::Char

    INTEGER::Char

    CONTINUOUS::Char

end

const vtype = Vtype('B','I','C')?

Checkout my package: https://github.com/mauro3/Parameters.jl. Maybe of
use.

Putting it in a module is fine if you want to regroup these under the
same namespace. That's the standard practice with enums too (when
constants correspond to integer codes, which isn't the case here).

Is there going to be overhead if I create constant group modules and use them via module_name.abc?

Not that I know of.
