should work on rust version1.72.1 also

Additional Context

No response

Debug Output

clap = { version = "4", features = ["derive", "cargo"] }

[epage]

This states it should work on 1.72 but doesn't say why.

[satyakommula96]

@epage is there way to get full verbose output?

[epage]

Verbose output of what?

[epage]

Without further information, I'm closing this. Our MSRV policy is N-2 so it is within that policy to support 1.74
