-
-This is due to
-
-```julia
-function parsefile(path::AbstractString; kwargs...)
- ext = lowercase(splitext(path)[2][2:end])
- return parsefile(Val(Symbol(ext)), path; kwargs...)
-end
-```
-
-and, specifically,
-
-```julia
-return parsefile(Val(Symbol(ext)), path; kwargs...)
-```
-
-Alternative #1: have `parsefile` extract the extension and use either `if`-`else` or indexing a `const Dict` to return `parsecsv, parseply`, etc.
-Alternative #2: use a polymorphic approach; do static dispatch on types, each associated with a file extension (e.g. `CSVFile`, `PLYFile`)
-
-If we ever wish to move to a structure that is easier to modify by a third user, we can implement a registry pattern of sorts.
-
-Turns out that `@report_opt CSV.File(path)` yields a bajillion errors on its own.
-At least we're not dispatching on `Val` now.
