<?php | |
$names = ['Alice', 'Bob']; | |
// PHP Closures | |
$greetings = array_map( | |
function($x) { | |
return "Hello $x"; | |
}, $names); | |
// HHVM's short-lambda version | |
$greetings = array_map($x ==> "Hello $x", $names); |
Or you can do the same thing, without having to expose your codebase to eval:
<?php
$result = false;
$procedure = [
'minifiy',
'reduce',
'squish',
];
foreach ($procedure as $call) {
$result .==> $call();
}
return $result;

Perhaps the parameter into ==> can be aliased as ~ ?
And with PSR7 can we reduce the request to $__ ?
