In Magento 2, you can configure a "virtual type" in a module's di.xml configuration file. These virtual types allow you to change the arguments of a specific injected dependency.

In the core Magento 2 code, there appears to be two naming conventions for virtual types. In the first, a virtual type has a name that appears identical to a real PHP class name.

#File: app/code/Magento/CatalogRule/etc/di.xml
<virtualType name="Magento\Catalog\Pricing\Price\Pool" ...

in the second, a simple, backslash-less string is used

#File: app/code/Magento/CatalogSearch/etc/di.xml
<virtualType name="advancedSearchFilterList" ...

Is there any practical difference to the above two naming conventions? i.e. does the name you chose for a virtualType have any impact on its behavior, or is it just a globally unique string that identifies the type so you can use it later on.

The name of virtual type is just a globally unique string. There is no difference in behavior for differently named virtual types. We just don't have strong naming convention for virtual types. I personally prefer second approach because it makes it obvious that this is virtual type, not a real class.

    This being a 1.5 yo post, is the conventions still that there is no convention? I should use what ever I want for virtual types, but you still encourage me to use the second approach? Or do you have a new standard by now? – Marius Oct 14 '16 at 7:50
