Using go fix to modernize Go code

Nice to knowtooling

What changed: Go 1.26 introduces a new implementation of go fix that can help modernize code.
Production impact: The source does not say.
Try it: Run go fix -r on a legacy Go file and observe the suggested changes.
Source: go.dev/blog/gofix

Understand it, then run it

Run it now

Todaygo

// This program demonstrates the newexpr modernizer feature introduced in Go 1.26.
// It uses the new function with an expression argument and prints the result.
package main

import (
	"fmt"
)

func main() {
	// new(10) creates an int variable initialized to 10 and returns its address.
	ptr := new(10)
	fmt.Println(*ptr) // prints 10
}

What it printed when we ran it on Go 1.27.1

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.
