First, there are objective aspects to that perception. For example, Python affords trying stuff immediately through its REPL. When you commit it to “real” code, it just works. Opening an UTF-8 file is just `codecs.open`. Alas, there is Zope/Plone to serve as a counterexample.

Second, emotional reactions do affect how we, human programmers, perform. If I feel nice coding in Python, I am very probably more productive. If I hate XML configuration files, I'll be on my nerves when I write them and might perform poorly.

The relationship between a programmer and code is not (just) a mathematical thing and we really should stop seeing emotion as a cognitive defect and appreciate it as the evolutionary improvement that it indeed is.

(Sorry for ranting. I'm hungry.)
