I have found a lack of functionality of Constants, when using it with conditions placed in Constants.
Let me explain in simple snippet,

Working example:

Page Setup:

config.baseURL = {$protocol}{$context.live}

[globalString = IENV:HTTP_HOST={$context.develop}]
  config.baseURL = {$protocol}{$context.develop}
[global]

Page Constants:

protocol = http://

context{
  live = somepage.X.com
  develop = somepage.Y.com
}

Above code works fine, but when we moves this code to the Constants you see a problem with {$context.develop} in the line with [globalString = ..]

Not working example:

Page Setup:

config.baseURL = {$baseURL}

Page Constants:

protocol = http://

context{
  live = somepage.X.com
  develop = somepage.Y.com
}

baseURL = {$protocol}{$context.live}

[globalString = IENV:HTTP_HOST = {$context.develop}]
  baseURL = {$protocol}{$context.develop}
[global]

So it seems that conditions i Constants need a small upgrade to full works.
