Gc() function no longer exists?

New to Julia

I start up julia from the command line using 1.4.1 (from Debian packages) and run:

dlakelan@pingpong:~$ julia

julia> gc()
ERROR: UndefVarError: gc not defined

that seems odd? Or did explicit gc() disappear at some point and I’m just seeing old code examples on the net?

Or is this specifically because my .julia/config/startup.jl loads Revise?

Perhaps you’re looking for GC.gc()

probably! but that certainly wasn’t what was in the first 5 or 10 online examples I checked… did gc move to GC recently (ie. the last 2 years)?

This is a great example of why I suggested that help? should include deprecated items.
