Does this compile for you? For me it doesn't (latest Vala from git):

async.c: In function 'foo':
async.c:32: error: 'data' undeclared (first use in this function)
async.c:32: error: (Each undeclared identifier is reported only once
async.c:32: error: for each function it appears in.)
async.c:35: error: case label not within a switch statement
async.c:41: error: case label not within a switch statement
async.c: In function 'foo_co':
async.c:83: error: 'x' undeclared (first use in this function)
async.c:89: error: 'y' undeclared (first use in this function)
error: cc exited with status 256
Compilation failed: 1 error(s), 0 warning(s)
