Pdflatex produces a whole lot of mumbojumbo output while it is parsing 
the file. And errors are mixed between this all. You can use regexp 
patterns to grab the error messages and they are then displayed in a 
list, you can click on them and jump to the file and line number of the 
error.
But below the list of errors is the resulting output and it would be nice 
if that jumped to the error, so that you can see its context.

This would work indeed, although I have the feeling it's a bit overkill 
to do this with perl ;)

I use TeXniscope[1], which speaks a bit of applescript and is able to 
refresh the pdf.
