`alias.type` makes a new name for a type.

``` ucm
project/main> alias.type lib.builtins.Nat Foo

  Done.

project/main> ls

  1. Foo  (builtin type)
  2. lib/ (643 terms, 92 types)

```
It won't create a conflicted name, though.

``` ucm
project/main> alias.type lib.builtins.Int Foo

  ⚠️
  
  A type by that name already exists.

```
``` ucm
project/main> ls

  1. Foo  (builtin type)
  2. lib/ (643 terms, 92 types)

```
You can use `debug.alias.type.force` for that.

``` ucm
project/main> debug.alias.type.force lib.builtins.Int Foo

  Done.

project/main> ls

  1. Foo  (builtin type)
  2. Foo  (builtin type)
  3. lib/ (643 terms, 92 types)

```
