all variables are changed into literal values, like :
x *sin(y)*power + clock  into :
x*sin(y)*1.5+0.1333

no. Very basic pattern that I used to create mountains, parses 15 sec. on 
1500x1500

wouldn't adding 1 keyword be easier/nicer/more comfortable for users then 
writting scripts ? What if linux user want's to give it to un-expirienced 
windows suer (with fast machine) or vice-versa ?

no. Did You try any complex pattern function yet ? That would generate 
realy nice mountains ? Or wait, I will post litte example soon.

only if user wants to do so. I.e. I want to spare some of 60 GB HDD to 
increase rendering/parsing speed.

save .tga of 2d array of height_field - is this extremly complex for You ?

why ? I agreee .tga is better then raw data.
