Groovy has a rarely used shorthand syntax for constructors:

println Date[time:0] // same as new Date(time:0)
println Date[year: 118, month: 8, date: 3] // same as new Date(year= : 118, month: 8, date: 3)

  1. GROOVY-8602
    2. points out t= hat the safe args version isn't supported, e.g.:=

    println Date?[time:0]

    I was thinking= of closing this as won't fix since we only support this shorthand for = class constants.

    Any objections?

    Also, I noticed that the empty map isn't cater= ed for:

    <= div>println Date[:] // as per above, might be expected to be the same as ne= w Date([:]) or new Date()
// currently NPE:= Cannot get property '{}' on null object

=
So, the map isn't found and the expression becomes "println D= ate" which returns void and then we convert the map to a String and lo= ok for that property.

I realise this is a weird ed= ge case but I was thinking of creating an issue to fix this for consistency= (just Groovy 3). We already support this:

def map =3D [:]
println Date[*:map]

Let me know if you= have other thoughts.


Cheers, Paul.=
