MooseX::Meta::TypeConstraint::Structured - MooseX::Meta::TypeConstraint::Structured - Structured type constraints.
DESCRIPTION
A structure is a set of Moose::Meta::TypeConstraint that are 'aggregated' in such a way as that they are all applied to an incoming list of
arguments. The idea here is that a Type Constraint could be something like, "An Int followed by an Int and then a Str" and that this could
be done so with a declaration like:
Tuple[Int,Int,Str]; ## Example syntax
So a structure is a list of Type constraints (the "Int,Int,Str" in the above example) which are intended to function together.
ATTRIBUTES
type_constraints
A list of Moose::Meta::TypeConstraint objects.
constraint_generator
A subref or closure that contains the way we validate incoming values against a set of type constraints.
METHODS
validate
Messing with validate so that we can support niced error messages.
generate_constraint_for ($type_constraints)
Given some type constraints, use them to generate validation rules for an ref of values (to be passed at check time)
parameterize (@type_constraints)
Given a ref of type constraints, create a structured type.
__infer_constraint_generator
This returns a CODEREF which generates a suitable constraint generator. Not user servicable, you'll never call this directly.
compile_type_constraint
hook into compile_type_constraint so we can set the correct validation rules.
create_child_type
modifier to make sure we get the constraint_generator
is_a_type_of
is_subtype_of
equals
Override the base class behavior.
type_constraints_equals
Checks to see if the internal type constraints are equal.
get_message
Give you a better peek into what's causing the error. For now we stringify the incoming deep value with Devel::PartialDump and pass that
on to either your custom error message or the default one. In the future we'll try to provide a more complete stack trace of the actual
offending elements

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.
Here are some examples of what I've tried:

Hi all...
Well guys and gals, I jumped in at the deep end and found things that PERL cannot do by default.
Many tricky terminal escape codes are not catered for so I had to create workarounds.
One thing I searched for was this:

Well, guys I saw a question about GOTO for Python.
So this gave me the inspiration to attempt a GOTO function for 'dash', (bash and ksh too).

This is purely a fun project to see if it is possible in PURE... (3 Replies)
