it seems like

ProjectTree

is only inherited by

FileSystemProjectTree

also does anyone else find it confusing that this type seems to be PrójectTree, as in a Tree that pertains to the noun "project"; but all the

project_

functions in

<http://externs.rs|externs.rs>

seem to be "projéct_whatever", as in the verb "project"?

but I'm genuinely curious if there's a reason why we have that subclass split between

ProjectTree

and

FileSystemProjectTree

if there's not a good reason for it, I'd be tempted to combine them

the docstring says " Has two implementations: one backed by file system and one backed by SCM.". I'm not sure what SCM is here

and I can't find this other implementation. is this just an out-of-date comment?

i think you're right that it's out of date

"SCM" here probably refers to the

Scm

class

i saw your draft PR and it seems legit, not sure if it's out of draft yet
