I second that!
It's especially frustrating to get an error message along the lines of 
"parentheses do not balance". You KNOW that Stata knows where you 
screwed up, but it wouldn't tell (and -set trace on- isn't 
overwhelmingly helpful in this case either). And it can take forever to 
figure out the missing parenthesis (despite bracket matching 
capabilities of the text editors I use).

In any case, I'm hoping for a (virtual?) engine that runs Mata line by line for debug purposes, if you see what I mean... I hear this sort of thing is available to help people debug their C programs (or maybe C++?), for example... (I'm no computing language person so forgive me for not being clear...)
