Is there concept of "since" in any programming language?

We see this in programming all the time. if condition result end

On the other hand, I'm not sure if since statements are used in programming. since result some cause end

I understand that since a result can be written in if condition because since statements themselves are conditional statemetns. However, in dealing with problems, we sometimes do observe the end result without knowing why that result was caused.

For example, in politics, politicians know their approximate popularity, but calculating which issues affect how much of popularity is a different problem all together. Such an event could be programmed like this.
since approximate popularity politician popularity = economy * x + foreign policy * y + health care * z + ... end

These applications are countless in the world. In the past, computers were not powerful enough to calculate any problem of this magnitude. They first were not being able to find out about the result such as an approximate popularity of politicians accurately. This isn't the case at all today. Google Trends is a great way to find out popular topics of the day that involves massive computing of counting several hundred millions of queries per day

So couldn't there be a compiler that automatically understand since syntax?
