Enough context can be provided later.
template get(alias a)
{
alias a!int get;
}
template foo(fun...)
{
alias get!fun foo;
}
void main()
{
alias foo!(a=>a) a;
assert(a(1) == 1);
assert(a(1.0) is 1.0); //NG
}
Note, this is reduced from how map and unaryfun works. If you turn it into
context-independent error, this would mean code break for some usages which are
currently accepted.
