eval(parse()) is neither secure nor robust. If you know variable names, you should get()/mget() them, e.g.,
mget(nasdaq100_symbols) |>
lapply(`[`, 6) |>
as.data.frame()
However, when you have to use mget() to process data, you may have to rethink your data structure: https://yihui.org/en/2023/04/get-objects/
