This is a feature of the C++ languange. Since it can't be determined
until instantiation of the class what class1<Type>::insideStruct
really is it needs to be qualified with the typename keyword (struct
obviously works too). See this link for a more thurough explanation: http://pages.cs.wisc.edu/~driscoll/typename.html

Unsurprisingly, this doesn't work as you cannot use a template class
without specifying the actual type parameter.
Indeed, the compiler complains on this with :
/.../main.cpp:24: error: 'template<class Type> class class1' used
without template parameters
/.../main.cpp:24: error: ISO C++ forbids declaration of
'insideStruct' with no type
/.../main.cpp:24: error: expected ';' before '*' token
(also, in my original code, the comments were reversed: the line
without "struct" is rejected, while the line with "struct" compiles
fine).
