Issue ID: 23931
Summary: Improve unhelpful error message
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P1
Component: dmd
Assignee: [email protected]
Reporter: [email protected]
The compiler emits an unhelpful diagnostic error message:
fail_compilation/test20245.d(69): Error: reference to local variable `this`
calling non-scope member function `this.this()`
for this file in the test suite:
compiler/test/fail_compilation/test20245.d
since commit:
https://github.com/dlang/dmd/commit/bd2bdae5e0e3ace7eb6eab69d5ebcd77c0dd8d28
The problem is that the message doesn't provide enough information for the user
to understand the problem.
One possible improvement would be:
fail_compilation/test20245.d(69): Error: reference to member variable
`DontDoThis.content` possibly escaped when passed to non-scope member function
`Exception.this()`
