How to avoid new lines caused by conditional expressions?

Question

Given this Go text / template code:

Let say:
{{ if eq .Foo "foo" }}
Hello, StackOverflow!
{{ else if eq .Foo "bar" }}
Hello, World!
{{ end }}

We get the following result if Fooequal to "foo":

Let say:

Hello, StackOverflow!

(followed by a new line)

Is there a way to get rid of extra lines of a new line?

I would expect this to be possible with the syntax {{-and -}}:

Let say:
{{- if eq .Foo "foo" }}
Hello, StackOverflow!
{{- else if eq .Foo "bar" }}
Hello, World!
{{- end }}

However, this leads to an error illegal number syntax: "-".
