But having to interact with it once in a while is always a hurdle. The same with bash. Do I use [ or [[? Where does the semi-colon go? if then fi, but while do done (and not elihw). -eq or =? Functions have () but no parameters.
I'm sure those things make sense when all you write is Bash / Perl, but it's daunting.
Now, Python can get pretty far out there too with Meta-programming, and JavaScript can get confusing with prototyping. And Ruby (especially RoR) takes the crown, where they resolve variables at the moment the line executes. Makes debugging blocks really hard.
The less magic in code the better.
Not really. Bash is known to be incoherent (due to legacy). You eventually getting accustomed to its quirks but they still remain absurd and may unexpectedly bite you someday. Perl code can, and perhaps will (it's humorously referred to as a write-only language afterall), get hard to read but at least is more robust.
