Create a single-file F# implementation

[adamchester]

It should have the following capabilities, in order of importance to me:

• [X] Formatting a template string [#7]
• [x] Destructuring and formatting of destructured values
• [x] Capturing properties (e.g. Name * Value) from a template
• [X] Parsing a template string [#7]

The API might look like this:

/// Formats a message template as a string, replacing the properties
/// with the provided values, writing to results to a TextWriter.
val formatf: provider: System.IFormatProvider
            -> tw: System.IO.TextWriter
            -> template: Template
            -> values: obj[]
            -> unit

/// Formats a message template as a string, replacing the properties
/// with the provided values.
val formats: provider: System.IFormatProvider
            -> template: Template
            -> values: obj[]
            -> string

/// Captures the properties f
val captureProperties: messageTemplate:Template -> (PropertyData * obj) seq

/// Parses a message template string.
val parse: templateString:string -> Template

It should be easy to simply copy the file into a project and use it.

It should be fast.
