Understand it, then run it

Run it now

Todaygo

package main

import (
	"debug/pe"
	"fmt"
)

func main() {
	// In Go 1.27.1 the type `pe.ImportDirectory` still exists but is marked deprecated.
	// This program creates a zero value of that type and prints it to show the API is usable.
	var dir pe.ImportDirectory
	fmt.Printf("zero ImportDirectory value: %+v\n", dir)
}

What it printed when we ran it on Go 1.27.1

zero ImportDirectory value: {OriginalFirstThunk:0 TimeDateStamp:0 ForwarderChain:0 Name:0 FirstThunk:0 dll:}

Run sends this program (for Solidity, the contract and its tests) to our own sandbox, where it is compiled and run once, with no network, and what it printed or the test report comes back here. Nothing is kept. Runs are counted per visitor for the day so everyone gets a turn; the details are on the legal page.
