<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#44546A">+1 on the idea.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#44546A"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#44546A">I wonder if full-blown “import” is overkill for the desired effect. Many languages simply allow you to de-qualify a namespace within a smaller scope. I’m thinking
of C++ at the moment: { using namespace std; … }<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#44546A"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#44546A">I think this would be preferable because it would still require that a module declare its “import dependencies” in a known place. I’m imagining chaos from large
source files with several dozen import dependencies, but only a few of them defined in the “normal” place.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#44546A"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#44546A">That said, there is syntactical boon from re-using the “import” keyword. Yet I don’t think it’s a stretch to make inlined imports be constrained by the module’s
imports. It’s a simple compiler error: “Foo cannot be imported inline because it is not imported by the module”.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#44546A"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#44546A">With or without the constraint, this would be an excellent feature.<o:p></o:p></span></p>

<p class="MsoNormal">This would be really handy to have. You could also have import "blocks", like<br>

<span style="font-family:"Courier New"">import Foo in {<br>
