Golang常数2D数组语法失败[重复]

Question

This question already has an answer here:

• Declare a constant array 4 answers

I want to declare a constant golang 2d array (not slices), but I can't figure it out, having looked at the other golang comments on this issue.

type fooT [1][1]float64
const BAR fooT = {[1]float64 {.01}}

Gives the error fubar.go:5: syntax error: unexpected {. But the following compiles fine:

type fooT [1][1]float64
var BAR = fooT {[1]float64 {.01}}

First, I do not understand why I need to redeclare the underlying array redundantly, and it does seem golang compiler knows the type because it gives an error if I change it. But, why can I not make this array a const? it is R/O, not a global.

And, the syntax is cumbersome.

From the specs:

Constants

There are boolean constants, rune constants, integer constants, floating-point constants, complex constants, and string constants.

IOW, in Go no {struct,array,slice,map,interface,pointer} constants exists.
