Moldable Exceptions
summary
Claim: exceptions carry contextual tooling so the debugger swaps in custom views and actions attached to the exception object. Implementation: a GT view pragma on exception methods reuses the object inspector and debugger UI, provides retry/fix‑it actions and conditional views. Specs: views average avg 12 lines of DSL, GToolkit already hosts ~3,000 views and the prototype has ~30 moldable‑exception examples. Result: lightweight, reusable domain‑specific debugger extensions that work and are far cheaper than prior extensible debuggers.
