This directory contains a number of design documents for TT3. They were written in no particular order.

• 01 - Lower Case Keywords

  Keywords will be lower case in TT3 by default.

• 02 - Context Free Grammar for Commands

  Keyword-based commands (i.e. directives in TT2) will be parsed by a context free grammar used to parse all expressions. The end result is that keywords will be recognised anywhere that variable expressions are recognised.

• 03 - The "Fat Arrow" Pair Constructor

  TT3 will use the "Fat Arrow" => operator in the same way that Perl does: the automagically quote a bareword on the left.

• 04 - Blessing Named Parameters

  When TT3 passes a hash array of named parameters to a subroutine or method, it will first bless them into the Template::Type::Params class so that the called code can tell them apart from a regular hash reference passed as a positional argument.

• 05 - Hash Items and Virtual Methods

  TT3 will have (at least) one way to explicitly access a hash item or call a virtual method (but not both).
