Yes, the '@' etc in the symbol names are part of the name-mangling scheme.
It allows type-safe linkage, since you get different decoration of the
name depending on parameter count and types, returned data type and
calling model.
Note that different compilers might use different name mangling schemes,
making it impossible to cross-link modules compiled by different
compilers.
