| • | One
of the most serious drawbacks of function templates |
|||||||||
| is
the danger of generating an instance of the function |
||||||||||
| that
is incorrect because of type conflicts. |
||||||||||
| • | Except
by writing specialized template functions to take |
|||||||||
| care
of such cases, there is no way to protect the client |
||||||||||
| from
using the function incorrectly, causing erroneous |
||||||||||
| instances
of the function to be generated. |
||||||||||
| • | Be
very careful when writing function templates to |
|||||||||
| ensure
that all possible combinations will create correct |
||||||||||
| functions. |
