Is the *Expr returned from Compile thread-safe?

Hi,

First, thanks for the library. I want to cache the compiled expression and use it concurrently across threads. Is this possible?

See this feature in the .Net version. https://github.com/mikhail-barg/jsonata.net.native

Thanks

i've checked for you and no it is not

passing a mutex or semaphore wrapper around it will enable you to use it concurrently although slower

package racechecker

import (
	"testing"
	"github.com/blues/jsonata-go"
)

func TestRace(t *testing.T) {
	jsnt := replaceQuotesAndCommentsInPaths("$$")

	e := jsonata.MustCompile(jsnt)

	for i := 0; i < 500; i++ {
		go func() {
			e = jsonata.MustCompile("$$")
			_, _ = e.Eval("{}")
		}()
	}
}
