No. No. NO. NO. NO!
A language has a certain syntax. Knowing that syntax is the responsability of the person who says "I know language XXX". It is not my responsability to make sure that I dumb down my code for your inability or unwillingness to keep your end of the bargain!
I'm currently in a shop where use of $_, map, and grep is nominally discouraged. Why? Because others might not understand the code later down the line. (Yet, this place uses the most complex regexes I've ever seen, making me go to my book over and over.)
If I was in C, would you discourage bit-masking? What about pointer arithmetic? Yes, they can cause problems, but they're a feature, not an 'oops'!
Let me take another tack. Let's say you told me "I can read English". So, I write you a letter in English. No problems, right? Well, you start complaining about my use of the words with more than 6 letters. They're too difficult. You've never seen them. You don't like them. (And, yes, I've received this complaint before!) Should I not use a standard part of the language you have said you speak solely because you don't want to make good your assertion?!?
I didn't think so.
Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.
