Duplicate command token

Reproduction

Command names and aliases share one application-wide namespace:

src/commands.ts

import { Command, Container, Handler } from 'func'

@Command({ name: 'build' })
class BuildCommand {
  @Handler()
  run() {}
}

@Command({ name: 'build' })
class RebuildCommand {
  @Handler()
  run() {}
}

new Container([BuildCommand, RebuildCommand])

How to fix it

Give every command name and alias a unique token:

src/commands.ts

@Command({ name: 'build' })
class BuildCommand {
  @Handler()
  run() {}
}

@Command({ name: 'rebuild' })
class RebuildCommand {
  @Handler()
  run() {}
}

new Container([BuildCommand, RebuildCommand])
