Can someone explain why
obj_size behaves differently than base
library(lobstr) x <- runif(1e6) y <- list(c(x), x) z <- list(x, x) all.equal(y, z) #>  TRUE object.size(y) #> 16000160 bytes object.size(z) #> 16000160 bytes obj_size(y) #> 16,000,160 B obj_size(z) #> 8,000,112 B

In the docs I see:
- Accounts for all types of shared values, not just strings in the global string pool.
