But in the present, the message is a bit misleading, since it must not necessarily be a string: $foo = function() {echo "bar";}; I consider this to be a very minor thing, but consider the message wrong, anyway. Reproduce code: --------------- function badLambdaCreator($argument) { function($test) use ($argument) { /*Do something*/ }; /*No return given :O*/ } $foo = badLambdaCreator(10); $foo(50); //Fatal error telling you to use strings, //while a lambda is fine too. Expected result: ---------------- A fatal error that also includes lambdas (I guess callbacks work? I'm not sure what name is the most appropiate). Actual result: -------------- An error that tells you that **ONLY** strings can be used. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=49555&edit=1
