class
   Crystal::Macros::MagicConstant
  
  
    
  
    Overview
  
  A pseudo constant used to provide information about source code location.
Usually this node is resolved by the compiler. It appears unresolved when
used as a default parameter value:
# the `__FILE__` here is a `MagicConstant`
def foo(file = __FILE__)
  # the `__LINE__` here becomes a `NumberLiteral`
  __LINE__
end
