It's always \[undefined index\] somewhere in PHP.

McValidator is written to provide a way to validate and sanitize data

Example 1:

```
use McValidator as MV;

// Builder is important because we can chain validator with them without
// too much work.
$builder = MV\valid('rule/is-string');

// Build the pipe
$pipe = $builder->build();

// Pump the value through the pipe
// Result contains the value and also informations about
// the runtime, such as errors and messages
$result = $pipe->pump(10);

// Gets the runtime state
$state = $result->getState();

// Gets the message of the head(first item) of errors
echo $state->getErrors()->head()->getMessage(); // Value is not a string

// We need more!
$builder2 = MV\shape_of([
    'a' => $builder
]);

$pipe2 = $builder2->build();

$result2 = $pipe2->pump(dict([
    'a' => 10
]));

// Gets the runtime state
$state2 = $result2->getState();

// Gets the message of the head(first item) of errors
echo $state2->getErrors()->head()->getMessage(); // outputs `Value is not a string`

// Gets the field path of the error!
echo $state2->getErrors()->head()->getStringPath('/' //
