Smalltalk questions are extremely appropriate here.
(Smalltalk at: #ConfigurationOfOmniBrowser) project lastVersion load: #( Dev )
The #( Dev ) in this context is a literal array that contains one element, the symbol #Dev. I'm not sure why #Dev is the thing that the last version of the ConfigurationOfOmniBrowser project is supposed to load, but it is certainly a legal Smalltalk expression.
