Coccinelle

[bearophile]

Sometimes D changes, and this requires many simple changes in Phobos. In such and other cases to save some time I suggest D developers (Walter too) to take a look at the free Coccinelle tool:

I think Coccinelle works on D code too (untested). It allows to define safe semantic patches, that despite being very short, are able to patch lot of code in seconds. Coccinelle looks useful for DMD/druntime too.
