Build Errors Don't Stop Execution

What steps will reproduce the problem?
1. Create a simple program
2. Save + Run
3. Create a syntax error
4. Save + Run again (old version runs)

What is the expected output? What do you see instead?
Switching to the "Problems" tab and not running the program at all would be 
great, but it seems like there should at least be a popup saying something like 
"There were build errors. Would you like to continue with the last working 
build?" Or even both (switch to "Problems" if an auto build fails and show a 
popup when you try to run a program that doesn't currently build).

What version of the product are you using? On what operating system?
GoClipse: 0.7.6.v439
Go: 1.1beta2
Windows 7 / amd64

As a new Go user I'm liking this plugin so far, but it's a little disconcerting 
that the IDE doesn't yell at me when I screw up and just silently runs the last 
version of my program that did compile.
