[Pharo-project] Smalltalk at: #Foo - needs clarification

Hello, just wanna ask, is this part of API will be deprecated in future? (in Pharo, it put under 'to clean later' category). And if yes, then what will be correct (dialect-agnostic) way to access globals? Smalltalk globals at: #Foo ? I thought that #at: #at:put: (and some others) historically is a part of Smalltalk protocol, and should stay there to support legacy code and cross-dialect code. What you thoughts about it? -- Best regards, Igor Stasenko AKA sig.
