[Pharo-project] allowUnderscoreAsAssignment broken ?

Tried in Pharo 1.4. Scanner allowUnderscoreAsAssignment ->> true. I then try to compile: testUnderscore | a | a _ 'a'. self assert: a equals: 'a' And I get: testUnderscore | a | a _ Nothing more expected ->'a'. self assert: a equals: 'a' thanks -- Mariano http://marianopeck.wordpress.com
