Those two snippets are not equivalent.

You're not assigning your byte to ulong; you're assigning the expression

The D tour for structs uses a syntax similar to that of C++ in
order to initialize a Person struct : Person p(30, 180). Is this
syntax supported in D ? Running that part of the code neither
works on the playground nor on my machine (dmd v2.076.0).
