Yes. This applies to all definitions inside a function, not just 
aliases.

Scope of 'alias'

[DLearner via Digitalmars-d-learn]

>>>
void foo(pint p1) {
   alias pint=uint;
   import std.stdio;
   writeln("p1 = ", p1);
}

void main() {
  alias pint=uint;
  pint var1;
  var1 = 7;
  foo(var1);
}
<<<

Does not compile.

But the rather similar:



alias pint=uint;

void foo(pint p1) {
   import std.stdio;
   writeln("p1 = ", p1);
}

void main() {
  pint var1;
  var1 = 7;
  foo(var1);
}
<<<

Is fine.

So 'alias' only valid from definition to end-of-function, rather 
than whole function?
