Package `astcopy` implements Go AST reflection-free deep copy operations.
## Installation:
Go version 1.16+
```bash
go get github.com/go-toolsmith/astcopy
```
## Example
```go
package main
import (
"fmt"
"go/ast"
"go/token"
"github.com/go-toolsmith/astcopy"
"github.com/go-toolsmith/astequal"
"github.com/go-toolsmith/strparse"
)
func main() {
x := strparse.Expr(`1 + 2`).(*ast.BinaryExpr)
y := astcopy.BinaryExpr(x)
fmt.Println(astequal.Expr(x, y)) // => true
// Now modify x and make sure y is not modified.
z := astcopy.BinaryExpr(y)
x.Op = token.SUB
fmt.Println(astequal.Expr(y, z)) // => true
fmt.Println(astequal.Expr(x, y)) // => false
}
```
