Following the release of *BPatterns
<https://github.com/dionisiydk/BPatterns>*, I am happy to share another
idea that naturally grows out of it: *simplifying deprecations in Pharo*.
Today’s deprecations are powerful but verbose—string-based rewrite rules,
duplicated selectors, and boilerplate that most of us copy from examples.
With BPatterns, all of this can be eliminated:
Object>>confirm: queryString
^ self *deprecatedBy: * [ ConfirmationRequest signal: queryString ]
Deprecation is now expressed in the same language as the code itself, not
in a separate, string-based mini-language. There is no need to think about
transformation rules—they are part of the system and enabled by default.
Zero boilerplate.
No duplicated code
