Dfr:
auto vtypes = map!(to!Variant[string])(lols);
The short template instantiation syntax only supports a single token, to avoid mistakes,so you need to add ():
map!(to!(Variant[string]))(lols); That is better written: lols.map!(to!(Variant[string])); But I don't know if this is enough to fix your code. Bye, bearophile
