Macro expansion (1.0.2.3 – 1.0.2.7)

An important internal change concerning the data format has been made: macro expansions and function applications like

are now replaced by hard-coded tags

Moreover, functions have systematically been replaced by macros. The few built-in functions which may take an arbitrary number of arguments have been rewritten using the new xmacro construct. If you ever wrote such a function yourself, then you will need to rewrite it too.

The new approach favorites a uniform treatment of macros and functions and makes the internal representation match with the corresponding Scheme representation. More and more information about tags will gradually be stored in the D.R.D. (Data Relation Definition). This information is mostly determined automatically using heuristics.

Notice that some perverse errors might arise because of the above changes. Please keep copies of your old files and report any suspicious behaviour to us.
