Variadic args and flags

[airtonix]

I see the usage spec very briefly and sneakily indicates that (so far) only args support multiple values.

but two questsions:

• what are the chances of supporting --foo blue --foo red so that $usage_foo is blue red
• with usage@2.2.2 the #USAGE arg "<foo...>" doesn't seem to work in mise file tasks.

Hi @airtonix

have you tried it with var=#true and the latest release of usage?

The following test from the code base does what you're asking for, doesn't it?

multi_flag:
    spec=r#"
    flag "-v --vars <vars>" var=#true
    "#,
    args=r#"--vars a --vars "b c""#,
    expected=r#"{"usage_vars": "a 'b c'"}"#,
