Certain symbols are parsed as operators, and others are parsed as identifiers. This is independent of whether that symbol is defined in Base. For example α is parsed as an identifier (which is not defined in Base). ± and ⊕, on the other hand, are parsed as binary operators (which are also not defined in Base). For something parsed as a binary operator, if you want to give it a definition you should define it as a two-argument function, e.g. ⊕(x,y) = x .+ 2y .... then e.g. a⊕b will correspond to the function call ⊕(a,b).
