Cannot convert an object

[n10v]

I make TOML support for nicksnyder/goi18n library, but become an issue when trying to marshal some objects: cannot convert type *translation.template to TomlTree. *translation.template have String method though, so we can use it for marshaling.

Code:

m, ok := v.(map[string]interface{})
if !ok {
    return nil, fmt.Errorf("invalid format for marshaling to TOML")
}
tree, err := toml.TreeFromMap(m)
if err != nil {
    return nil, err
}
s, err := tree.ToTomlString()
return []byte(s), err

Example of m:

map[person_unread_email_count:map[one:{{.Person}} has {{.Count}} unread email. other:{{.Person}} 
has{{.Count}} unread emails.] person_unread_email_count_timeframe:map[other:{{.Person}} has 
{{.Count}} unread email in the past {{.Timeframe}}.] program_greeting:map[other:Hello world] 
your_unread_email_count:map[one:You have {{.Count}} unread email. other:You have {{.Count}} 
unread emails.] d_days:map[other:this should get overwritten] my_height_in_meters:map[one:I am 
{{.Count}} meter tall. other:I am {{.Count}} meters tall.] person_greeting:map[other:Hello 
{{.Person}}]]

Sometimes I become failed to marshal en-us strings to toml: map key needs to be a string, not language.Plural, but language.Plural is just a string:

type Plural string
