I think you should learn Python, that way, you will appreciate the good things in Pascal !
As much as I don't like Python, I agree. Not only to appreciate Pascal more, but because Python is so widely used it can be very detrimental and limiting not to know it well, and also not be able to use it well.
Another recommendation would be, learn C and C++. Knowing Pascal, C will be fairly easy to learn. C++ is a different ballgame, the reason I recommend learning it is because more and more basic programming examples are written using it (particularly using its libraries). Not knowing C and C++ is quite a handicap. Just for the record, I very strongly dislike C and dislike** C++ but, learning them will make you appreciate Pascal even more 
I agree, Not knowing C/C++ (moreso C) is quite a handicap, and while it is not same category as Python, it can be very detrimental not to know it.
And, like with Python, learning and C/C++ will highlight a lot of what Pascal does better.
Also, learning both C/C++ and Python will expand your "toolkit" as far as what you can do in Pascal.
Both by doing things natively in Pascal you would have not done before, and also by leveraging C libraries.
And with Python, as Alex pointed out, being able to write plugins for SublimeText and FPC/Lazarus programs like CudaText.
