#ifndef(array[index])
...
#end
or, alternatively, some way to convert strings to identifiers, like
this:
#declare iteration=0;
#while(iteration<10)
#ifdef(concat("variable_",str(iteration,0,0)))
...
#end
#declare iteration=iteration+1;
#end
...which would allow me to see if variable_0, variable_1, variable_2
etc. has been declared.
