Re: [Vala] array declaration

[Seth Hoenig <seth a hoenig gmail com>]

My opinion matter not, but it makes more sense to me to force the ' type[]
name = new type[] ' syntax.
Not only does it make more phonetic sense, but it also eliminates ambiguity
when using the 'var name = new type[]'  syntax. (If the other syntax were
allowed, would var name[] = new type[] be correct or would var name = new
type[] be correct?).
