<p>Olabini: /* languages with guaranteed TCO */</p> <hr /> <div>Are tailcalls fated to come in second place on every feature priority list?<br /> <br /> Let's gather the use cases and consider the implementation.<br /> <br /> (Note: This page is about &quot;hard tail calls&quot; as defined in the [http://blogs.sun.com/jrose/entry/tail_calls_in_the_vm Rose blog]. Soft TCO is already in many compilers, but does not have a strong effect on software architecture.)<br /> <br /> == use cases ==<br /> === multi-core task distribution ===<br /> (Doug Lea) chaining task execution; without tail calls you blow the stack needlessly<br /> <br /> === languages with guaranteed TCO ===<br /> These are languages with functional patterns, including Scheme, Scala, F#. Seph also aims to give this guarantee.<br /> <br /> == external links ==<br /> ;Proposal: http://blogs.sun.com/jrose/entry/tail_calls_in_the_vm<br /> ;Thesis: http://www.ssw.uni-linz.ac.at/Research/Papers/Schwaighofer09Master/<br /> ;mlvm Wiki: http://wikis.sun.com/display/mlvm/TailCalls<br /> ;mlvm Code: http://hg.openjdk.java.net/mlvm/mlvm/hotspot/file/tip/tailc.patch</div>
