The length of the two arguments must match, or
one of them must be of length one. If the length of
one argument is one, then the output's length will
match the length of the other argument. See examples
below.

## Arguments

- lhs
Left hand side, character vector.

- rhs
Right hand side, character vector.

## Value

Concatenated vectors.

## Examples

```
"foo" %+% "bar"
#> [1] "foobar"
letters[1:10] %+% chr(1:10)
#> [1] "a1" "b2" "c3" "d4" "e5" "f6" "g7" "h8" "i9" "j10"
letters[1:10] %+% "-" %+% chr(1:10)
#> [1] "a-1" "b-2" "c-3" "d-4" "e-5" "f-6" "g-7" "h-8" "i-9" "j-10"
## This is empty (unlike for parse)
character() %+% "*"
#> character(0)
```
