I'm getting an apparently spurious warning, "ignoring unrecognized special parameter attribute ..." from ldc2 when passed the -w flag and using the @target attribute. Here's an example:

Code is generated correctly AFAICT when the -w flag is removed.

I resurrected my, forgotten, GitHub account and filed it. Thanks again Johan for the work you do on LDC.

You're right—this seems to be a warning triggered by LDC's stricter diagnostics when using -w, even though the code compiles and runs as expected. The issue likely stems from LDC not fully recognizing or supporting the @target("...") attribute syntax you're using.

You might consider filing a bug report or feature request with the LDC project if this isn't documented behavior. In the meantime, if -w is too noisy for your use case, a possible workaround is to suppress specific warnings if LDC supports that, or remove -w during development and enable it selectively in CI/testing.
