Am I interrupting my husband's parenting? when 'a*b' takes place .. The type of 'b' allows compiler to deduce 'xR' and 'yR' arguments. It appears that you expect the compiler to take 'c' into account.
I'm not looking for advice or lectures about why ints shouldn't be used in template parameters, so please don't respond with such. That not how it works in C++.

Argument deduction for function templates is always based on the types of actual function arguments and _only_ on these types. But when Itry to call the function from main, I encounter error C2783. What is wrong? This is the one giving error.
If we follow Richard's suggestion and add parentheses, then we are no longer subject to compiler whims. Argument deduction for function templates is always based on the types of actual function arguments and _only_ on these types. That's what the compiler is trying to tell you.

You need to pass this argument explicitly. In reality, the GetHelper function would try to deduce some constructor parameters of Helper at runtime, so this is why I used this design.

Default arguments cannot be used to deduce a template argument.The following sample generates C2783: Copy // C2783.cpp template
Same results as you for g++-4.8 and clang-3.2. –Nate Kohl Jan 18 '13 at 17:11 Thanks for the thorough analysis and the suggestion. Why is the FBI making such a big deal out Hillary Clinton's private email server? I'm just wondering what part of this C++ syntax is invalid. This is defined as such in the standard and if you think about it (in the general case) it makes sense.
