[Pharo-dev] Weird behaviour of Opal

Hi, When I enable OpalCompiler, and try to evaluate the following in a Workspace: ZnClient new systemPolicy; url: 'http://easy.t3-platform.net/rest/geo-ip'; queryAt: 'address' put: '81.83.7.35'; accept: ZnMimeType applicationJson; contentReader: [ :entity | NeoJSONReader fromString: entity contents ]; ifFail: [ ^ self inform: 'Sorry, Dave, cannot do that.' ]; get; response. I get a 'Name already defined' error on :entity, no matter how I name the block parameter. Well, it happens on [ :x | x + 1 ] value: 100. as well ;-) Sven
