Hi,
quite often you need to change a value relatively to another value.
For example:
array1[array2[i]] := array1[array2[i]] + 42;
Luckily this can be written as
array1[array2[i]] += 42;
Which is nice.
However, sometimes you do not need addition, but the minimum.
For example:
array1[array2[i]] := min(array1[array2[i]], 42);
Now, you need to repeat all the array indices.
Which is very ugly.
So there should be an alternative syntax, similar to += :
I.e.:
array1[array2[i]] min= 42;
Declare a custom function and mark it inline for efficiency. That also
allows you to document it properly, have different implementations
depending on the parameter types and so on.
There really are limits to the extent that the underlying Pascal should
be mangled further. Your time would be better spent trying to persuade
the core developers to tolerate extra operators like ⌊ for floor(), and
then working out how to implement them >:-)
array1[array2[i]] := array1[array2[i]] ⌊ 42;
array1[array2[i]] ⌊= 42;
