example how a for statement is declared
http://seed7.sourceforge.net/examples/declstat.htm

ok i know that seed is an interpreter language but maybe there is a way 
walter can allow something like this for his buildin statements

or even better the case statement

http://seed7.sourceforge.net/manual/stats.htm#case-statement

as a statement-template wich can produce (with the help of the awaited 
static foreach) a nice objectfactory from a tuple or something like this

Stuff like this has been requested several times, but the same problem 
prevents these suggestions from being implemented: they break the separation 
of syntactic and semantic analysis.  This increases the complexity of the 
compiler greatly.

Now, some level of "custom code" may become available if/when D gets 
Lisp-style macros, which will (hopefully) allow for custom generation and 
reorganization of code by other code.

You should be able to do this now with mixins, although its not the 
neatest way to do things.
