/*
    Since our quirky block definitions are basically a list of comma separated
    arguments, we need a wrapper in order for these definitions to be
    expanded before being used as arguments to the LAYOUT_xxx macro.
*/

/*
    Blocks for each of the four major keyboard layouts
    Organized so we can quickly adapt and modify all of them
    at once, rather than for each keyboard, one at a time.
    And this allows for much cleaner blocks in the keymaps.
    For instance Tap/Hold for Control on all of the layouts

    NOTE: These are all the same length.  If you do a search/replace
      then you need to add/remove underscores to keep the
      lengths consistent.
