However, prior to invention of [[Insight]] it was necessary to write your instruments in [[Java]]. Generating a [[Truffle]]-based language implementation compiled by [[native image]] may take a while. Recompiling everytime you want to change your instrument, slows you down significantly. That's not a problem for [[GraalVM]] [[Insight]] - all the hooks are written in dynamic language and compiled on the fly into the appropriate user code locations. There is no limit on what these hooks can do - [[Insight]] are fully [[Turing complete]] code snippets capable to do everything the surrounding programming language can.</ins></div></td></tr> <tr><td class='diff-marker'> </td><td style="background: #eee; color:black; font-size: smaller;"></td><td class='diff-marker'> </td><td style="background: #eee; color:black; font-size: smaller;"></td></tr> <tr><td class='diff-marker'> </td><td style="background: #eee; color:black; font-size: smaller;"><div>A promising direction of research is usage of [[Insight]] as a harness for post-mortem debugging.
