+The performance of many dynamic language implementations suffers from
+high allocation rates and runtime type checks.  This makes dynamic
+languages less applicable to purely algorithmic problems, despite their
+growing popularity.  In this paper, we present a simple optimization
+based on online partial evaluation to remove object allocations and
+runtime type checks in the context of a tracing JIT.  We evaluate the
+optimization using a Python VM and find that it gives good results for
+all our (real-life) benchmarks.
