So true ! Loved u'r violin example. Let me state my experience. I used to code in BASIC when I was in school, when shifting to C++ in college it was a pain in the ass. Later I learnt python by choice, although initially indentation stuff freaked me out. I had gotten used to C syntax. Recently while learning scheme I felt handicapped. Once we'r used to certain languages, familiarity makes the task seems easy. I found that Java code easier than scala because may be I'm unaware of scala syntax. The fact that almost everyone in the college codes in C++ because they are using it and they are so used to it that they feel problems while switching languages !!

PS. I'm much happier now that python had replaced C++ as my primary language :)
