library(parsnip)
library(survival)

# Create model and fit
survreg_fit <- survival_reg(dist = "weibull") |>
  set_engine("survival") |>
  fit(Surv(futime, fustat) ~ 1, data = ovarian)

out <- butcher(survreg_fit, verbose = TRUE)

# Another survreg object
wrapped_survreg <- function() {
  some_junk_in_environment <- runif(1e6)
  fit <- survreg(Surv(time, status) ~ ph.ecog + age + strata(sex),
                 data = lung)
  return(fit)
