quo() fails to capture certain syntactically valid expressions

[egnha]

In 0.2.2.9002, the following occurs:

quo(`/`(2))
#> Error in enquo(expr) : bad value

This also occurs for other arithmetic operators (e.g., *), but not all of them (e.g., ^).

Is this a bug?

(This is a rather special occurrence. Nonetheless, I have a DSL where I want to capture, then modify, such expressions, as quosures.)

@lionel- , thanks for fixing this.
