provide convenience helper function for constructing file:/// URIs?

[vtjnash]

For example, see code and tests in PR to URIParser.jl: https://github.com/JuliaWeb/URIParser.jl/pull/60/files#diff-6c68f903474362a5d56664b6304e491bR59

Seems useful.

I wonder if it should be URI(::Base.FilePath)?
i.e. instead of putting the type in the method name (URI_file), add a type for strings that represent a local file path. This would be generally useful in many places.
(But I wouldn't want to force people to say read(FilePath("myfile")) where they can currently say read("myfile")).

What's Base.FilePath?

julia> Base.FilePath
ERROR: UndefVarError: FilePath not defined

What's Base.FilePath?

... add a type for strings that represent a local file path.
