right clicking doesn't work right for assignment statements

[sumeet]

• left clicking on the variable should let you do a special menu

  • Edit variable name
  • "Unassign" the expression
  • Delete the entire expression

• You should be able to click on the expression (RHS of assignment) and change the expression

  • if the variable is being used somewhere, then the expression stay the same type (unless it's generic... but we'll get there later lol)
