Short args can't be used with =

Short args can’t be used with =. Is this intentional?

const arg = require('arg')

arg({
  '-a': String
})

node example.js -a=a

Results in:

                                        throw new TypeError(`Option requires argument (but was followed by another short argument): ${originalArgName}`);
                                        ^

TypeError: Option requires argument (but was followed by another short argument): -a
    at arg (<path>/node_modules/arg/index.js:97:12)
    at Object.<anonymous> (<path>/example.js:5:1)

A similar error happens for aliases:

const arg = require('arg')

arg({
  '--a': String,
  '-a': '--a'
})

Going to close this as I don’t think there’s anything actionable. Thank you for the input 😃
