Really liking the arrow functions in PHP 7.4 so far! Unfortunately already found one missing feature: you can't throw Exceptions from them. The following results in a 'unexpected T_THROW' syntax error:

fn() => throw new Exception('nope');

Would've cleaned up my test, but alas.

@nikita_ppv is this a bug or a feature request?

That's not an expression.

It's a feature request. "Throw" is a statement, not an expression. It could be made an expression...

Gotcha. Thanks for the reply :)

An expression should have a well-defined return value for propagation. I don‘t think throw qualifies in that sense and should therefore remain a statement, don’t you think?

Took a shot at it, turned out to be easier than expected. github.com/php/php-src/pu… Let me know what you think.
