==================== Summary ====================

Name: Tools-ct.1056
Author: ct
Time: 14 May 2021, 4:04:19.358396 pm
UUID: eac0462e-77bd-8a47-b585-929c7ec9cf2e
Ancestors: Tools-mt.1055

Relieves BasicInspector of sending any (non-inlined) messages to the inspected object. Fixes #testProtoObject from ToolsTests-ct.105. Now you can even inspect uninitialized FutureMakers. :-)

Depends on Kernel-ct.1404 (Context >> #objectIsReadOnly:).
