If you download D-Scanner and run "dscanner --styleCheck -R 
path/to/code" you can easily tell if the LastCatch syntax is 
being used. The message you get is "Catching Error or Throwable 
is almost always a bad idea."

If you find out that some code IS using this old syntax, this 
tool will fix it automatically:

# Run upgrade
dfix file.d > file.d.fixed
# Check that it worked as expected
meld file.d file.d.fixed
# Overwrite old file
mv file.d.fixed file.d
