The capabilities and productivity of "professional" programmers vary widely. Murnane, 1993) most research about the cognitive effects of computer programming seemed to have focused on programming as a problem solving rather than a linguistic activity. It matters because ultimately writing code is about discipline and details. If computer languages were To write a decent program, you have to discipline your brain *far* more than you would need with any language (because, let's face it, other people are forgiving but compilers or computers are not). Immutable Object Programming (IOP) enforces a discipline on the programmer, much like structured programming enforced a discipline on programmers. The discipline of computre programming has made considerable progress over the years. The short answer is an emphatic 'yes'. With a few notable exceptions (e.g. Does it really matter what the code looks like? Somewhere in the middle are the true software engineers, who approach computer programming in a disciplined and rigourous knowledge-based manner, similar to that of engineers in other fields.
