You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: value.go
    path of file: ./repos/expr/patcher/value
    
    the code of the file until where you have to start completion: // Package value provides a Patcher that uses interfaces to allow custom types that can be represented as standard go values to be used more easily in expressions.
package value

import (
	"reflect"
	"time"

	"github.com/expr-lang/expr"
	"github.com/expr-lang/expr/ast"
	"github.com/expr-lang/expr/conf"
)

// Value
    
func (patcher) Visit(node *ast.Node) {
	switch id := (*node).(type) {
	case *ast.IdentifierNode, *ast.MemberNode:
		nodeType := id.Type()
		for _, t := range supportedInterfaces {
			if nodeType.Implements(t) {
				ast.Patch(node, &ast.CallNode{
					Callee:    &ast.IdentifierNode{Value: "$patcher_value_getter"},
					Arguments: []ast.Node{id},
				})
				return
			}
		}
	}
}
