ref https://github.com/nim-lang/Nim/pull/25783 This pull request addresses an issue with addressability of tuple elements of type `lent` or `var` in Nim, ensuring that expressions involving these types are handled correctly during type changes. The main changes introduce a check to prevent attempting to change the type of tuple elements that are views (`var` or `lent`), and a new test is added to verify the correct error is raised when trying to take the address of such elements. Type system and semantic analysis improvements: * Added the `isViewTarget` template in `semexprs.nim` to check if a type is a view (`var` or `lent`), and updated `changeType` to skip type changes for tuple elements that are views. This prevents invalid addressability operations on these types.

This directory contains the test cases.
Each test must have a filename of the form: t*.nim
Note: Testament is only aware of tests under a directory (eg tests/foo/) and will ignore
top-level tests like tests/tbar.nim.
Specs
Each test can contain a spec in a discard """ ... """ block.
Check out the parseSpec procedure in the specs module for a full and reliable reference
action
Specifies what action this test should take.
Default: run
Options:
compile- compiles the module and fails the test if compilations fails.run- compiles and runs the module, fails the test if compilation or execution of test code fails.reject- compiles the module and fails the test if compilation succeeds.
There are certain spec keys that imply run, including output and
outputsub.
Categories
Each folder under this directory represents a test category, which can be
tested by running koch tests pcat <category> (or cat to avoid parallel
testing, which is slower).
The folder dll contains simple DLL tests.
The folder realtimeGC contains a test for validating that the realtime GC
can run properly without linking against the nimrtl.dll/so.
