Yes, AlgebraicDataType will be installed three times, Unification twice. 
This is because #install: is implemented as #addPackage:, then #install. 
Since the Installer subinstance is kept between #install sends, therefore 
the installations will repeat. The solution is to use #addPackage: and 
#install directly:

Installer cache
 	addPackage: 'AlgebraicDataType';
 	addPackage: 'Unification';
 	addPackage: 'Zippers';
 	install

or using a collection:

Installer cache install: #('AlgebraicDataType' 'Unification' 'Zippers')
