= Todo List =

 * create a testsuite

== Features ==
 
 * add "elsif" and "switch/case" in macro-language
 * add option for number of draw in Metropolis subsamples [parser + Matlab code]
 * add option for algorithm to solve generalized Sylverster equation [parser + Matlab code]
 * add new function diff(), sum loops and prod loops in modeling language. Should be unrolled. [parser]

== Error checking ==

 * add a check for number of equations and endogenous in the case of Ramsey policy
 * improve error message when dealing with Expr``Node::Eval``Exception (in particular for reporting in Model``Tree::evaluateJacobian)
 * add warning for missing variable in current period. This is permissible in some cases, Michel should write a note about it [parser]
 * improve error and warning handling in parser. Find a way that users see Warnings even if scrolling by [parser]

=== Checks concerning the structure of the mod file ===

 * allow a single histval, endval, initval block
 * check that a given parameter is never declared two times
 * check that observation trends is used after a varobs
 * add a warning if homotopy_setup block comes after steady

=== Checks concerning the types of variables allowed in expressions ===

 * varobs must be declared endogenous
 * shocks must be exogenous
 * objective_planner must be endogenous without leads/lags

== Optimizations / Enhancements ==

 * optimize expression sharing (for example use the fact that A+(B+C) = (A+B)+C); this would also enhance the pre-computing of numerical constants (for the moment, the algorithm can't reduce {{{1+(x+1)}}})
  * if there is a series of operators with the same precedence, we can collect the constant and reduce them {{{1+(x+2}=(1+2)+x=3+x}}}
  * but it is possible to factorize more complicated expressions: {{{2*x+3*x=(2+3)*x=5*x}}}. The two simplifications aren't identical but strongly related. -- MichelJuillard <<DateTime(2007-05-08T19:53:46Z)>> 
 * rewrite outputting system (by using a subclass of ostream containing the output type, and by overloading << operator)
 * improve internal representation of estimated_params* statements
