Ah right... good point

I don't see a missing dot there? There's only one between the two placeholders, right? In your screenshot it's at the end of the line.

Aside from that, I'm also unsure how I feel about using concatenation just to avoid escaping.
I don't have much against escaping, it's only a bit hard to read because it's not the backslash one is used to from everywhere else.
