@dump(file:string, variable_1, ... variable_p)

is a special form: the arguments variable_i are restricted to be variables. Calling this special form store the values of the variables in the file whose path is file. This function is a special form, so it cannot be curryfied.

The stored value can be restored using the function @loadvar. The dump file produced by @dump is in a human readable format and corresponds to a fragment of the Antescofo grammar.

The returned value is true if the value of the variable have been saved, false elsewhere (e.g. if file cannot be created). The process of saving the values is done asynchronuously in a dedicated thread, so the run-time computation are not perturbed.

The dump file can be produced during one program execution and can be read in another program execution. This mechanism can be used to manage presets.

Note that this special form expands into the ordinary function @dumpvar. The same comments apply.
