To avoid multiple identical messages in the console output.

Example:

library(lazyvec)

# create a wrapper around altrep sequence
z <- alt_wrap(1:100, "z")

# multiple messages, possibly from R code called from C++
length(z)
#> z : ALTREP length : result =  integer[1] 100
#> z : ALTREP length : result =  integer[1] 100
#> [1] 100

This feature is not required, as the listeners cannot access the lazyvec ALTREP that is calling them, just the payload.
