Hi guys.
I started to learn Apex recently.
Then I found that many things can be write with case insensitive character.
Such as:

• Object name:
  • You can write 

    public pagereference method1() { ..}

    instead of 

  • public PageReference method1() { ..}

• Variable name
  • This will be compile error

  • Integer I;
    Integer i;

• SOQL and SOSL statements

  • Account[] accts = [sELect ID From ACCouNT where nAme = 'fred'];

I refering to this : http://www.salesforce.com/us/developer/docs/apexcode/Content/langCon_apex_variables.htm

Just to make sure, are there other case-insensitive things that can be happen on Apex ?
