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.
