docs question

Does the first paragraph need to be rewritten?

I intend to submit a pull request pending clarification.

$ ed -s DataFramesMeta.jl/src/macros.jl <<<'2798, 2820p'
### Details

Both the left- and right-hand side of an expression specifying a column name assignment
can be either a `Symbol` or an `AbstractString` (which may contain apces) escaped with `
$DOLLAR`. For example `:new = ...`, and `$(DOLLAR)"new" = ...` are both valid ways
of assigning a new column name.

This idea can be extended to pass arbitrary right-hand side expressions. For example,
the following are equivalent:

```
@rename(df, :new = :old1)
```

and

```
@rename(df, :new = $("old_col" * "1"))
```

The right-hand side can additionally be an `Integer`, escaped with $(DOLLAR), to indicate
column position. For example, to rename the 4th column in a data frame to a new name, write
`@rename df :newname = $(DOLLAR)`.

How would you re-write? What do you think is wrong (aside from the obvious typo)

[spaette]

Perhaps I misunderstand the author's intent in that paragraph.

obvious typo

Were apces the typo would the fix possibly be either of ellipses or an ellipsis?

[spaette]

Aside from the correction of that paragraph the repo had a second typo.

$ grep -nr dont DataFramesMeta.jl
DataFramesMeta.jl/test/parsing.jl:125:    # Some errors when we dont have keyword arguments, since
$ 

[pdeffebach]

Sure. Please open a PR with these fixes.

@bkamins

Would you chip in on this ticket?

Looking at the string apces it occured to me the author's intent may have been spaces.

Otherwise the singular an ellipsis would seem more fitting than the plural ellipses.

[pdeffebach]

No need to ping Bogumil. You are entirely correct. Please open a PR with those changes.

[spaette]

entirely correct

Evidently not in regards to my interpretation of what you wrote in your comments.

Pull has been fixed with a soft reset performed.
