Go: proposal: Go 2: Permit running code at compile-time using "comptime" keyword

[donutloop]

Problem

I want to read in the content of files while compiling time to simplify the shipping of template files with a binary.

Solution

using the comptime keyword to run arbitrary code at compilation-time.

Ref: https://ziglang.org/documentation/master/#Introducing-the-Compile-Time-Concept

Design idea

func main() {
    content := comptime os.Open("./code.json")
   ....
}

We aren't going to permit arbitrary code to run at compile time.

The specific topic of embedding files in a compiled binary is #35950.

Also there is go generate which should be used instead for code generation.

For the reasons mentioned above, this is a likely decline. Leaving open for four weeks for final comments.
