Let's be clearer on the trade-off here. 

In the two examples quoted, 

	pairwise correlation matrix
	chi-square tests 

it happens that there are user-written 
solutions, but you have to 

1. Be lucky like that, i.e. something exists. 

2. Be very lucky, i.e. that something 
does exactly what you want. 

3. Find it. Despite aids and experience, this 
can be still be tricky. 

4. Trust the user-programmer. 

5. Be lucky again if you run into problems, 
that the user-programmer, or somebody else, 
will provide support. (StataCorp won't, 
on user-written programs.) 

With Mata, you have greater power to do it yourself. 

That said, user-programmers are not yet redundant!
