My intuition suggests thatRadio andSelect should behave identically apart from visual appearance. However,Radio only supports strings as key values. Thus,

@bind M Radio([M1 => "Diagonal Matrix", M2 => "Symmetric Matrix"])

does not work but

@bind M Select([M1 => "Diagonal Matrix", M2 => "Symmetric Matrix"])

does.

It seems this issues used to exist forSelect too, but it was fixed in#3. WasRadio perhaps forgotten?
