You're confusing two things here. Yes, if we never use void[] 
casts, pointers, goto statements ect, or at least study how they 
work, we're gonna be helpless. But D does not prevent using them, 
just makes you aware when you do.

For sure you won't learn to swim correctly with plastic pillows 
only, but that does not mean they have to be made so that they 
could break at any moment. It just means you have to take them 
off sometimes.
