Subject: Re: [PHP-DEV] Re: An implementation of a short syntax for closures

In terms of thinking about typos, I'm sure there would be a solution to 
making pretty robust short hand lambdas.

I think a more valid discussion would be whether PHP should have a short 
hand lamda notation. A lot of talk on here is against there even being a 
short-hand version, whatever syntax it is.

I'm really trying to continue the discussion in to coming up with a good 
syntax everyone likes. If there is a good syntax maybe people against 
the idea might change their opinion.

Personally I think it would be a good addition to the language. As other 
people have pointed out, a lot of common languages have a syntax for 
short hand lambdas. Also with the popularity of technologies such as 
LinQ increasing, I can see small lambdas becoming more and more common.

In regards to typos, I don't think the following bit of code would be 
too easy to put a typo in to?:

// Mapping:
$a->select( :($x)=> $x->getName() );
