## DFrameList ====
suppressPackageStartupMessages({
    library(IRanges)
})
dfl <- DataFrameList(
    "A" = DataFrame(
        "a" = c(1L, 2L),
        "b" = c(3L, 4L),
        row.names = c("aa", "bb")
    ),
    "B" = DataFrame(
        "a" = 5L,
        "b" = 6L,
        row.names = "cc"
    )
)
## Our variant, which assigns into columns.
x <- unlist2(dfl)
print(x)
## Compare with the standard variant, which modifies rownames.
y <- unlist(dfl)
print(y)
