  The problem is that if we want to keep the true case
of the symbols (which I at least want), doing case-insensitive 
searching required practically to lowercase on the fly
all pascal symbol each time an expression is evaluated.
  This is very inefficient.

  There are some internal functions or variables inside Free Pascal
that are lowercase to avoid possible conflict with
explicitly declared functions or variables (who are completely
UPPERCASED in Free Pascal).
  GNU pascal uses First Letter Capitalization for its
declared function/variables (I don't know the internals of GPC).  
  In the printout, I would like to keep this difference
between internal and declared variables.

  If I have an internal variable named stdout,
and a declared variable STDOUT.
  I would really prefer to still be able to
only get one matching variable if I use the exact matching 
stdout or STDOUT.
