Hi,<br>
<br>
With MethodHandles and VarHandles being the only safe way to access members<br>
across module boundaries for Java 11 and greater.<br>
How will the limits outlined here<br>
<a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_oracle_graal_blob_master_substratevm_LIMITATIONS.md-23invokedynamic-2Dbytecode-2Dand-2Dmethod-2Dhandles&d=DwIBaQ&c=RoP1YumCXCgaWHvlZYR8PZh8Bv7qIrMUB65eapI_JnE&r=CUkXBxBNT_D5N6HMJ5T9Z6rmvNKYsqupcbk72K0lcoQ&m=eB7NOfFFa-lNWC35epoJT1gnKeKzO4v-75i3-xj8iOA&s=-fRbUyYzG85Nd8Gb8E_fR0Zo8rqDRDzTWxFwOMqK2FM&e=" rel="noreferrer" target="_blank">https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_oracle_graal_blob_master_substratevm_LIMITATIONS.md-23invokedynamic-2Dbytecode-2Dand-2Dmethod-2Dhandles&d=DwIBaQ&c=RoP1YumCXCgaWHvlZYR8PZh8Bv7qIrMUB65eapI_JnE&r=CUkXBxBNT_D5N6HMJ5T9Z6rmvNKYsqupcbk72K0lcoQ&m=eB7NOfFFa-lNWC35epoJT1gnKeKzO4v-75i3-xj8iOA&s=-fRbUyYzG85Nd8Gb8E_fR0Zo8rqDRDzTWxFwOMqK2FM&e=</a><br>
be effected.<br>
I assume as a minimum things such as MethodHandle.Lookup.unreflect* and<br>
MethodHandle.Lookup.find* will work for runtime reflected members?<br>
<br>
Cheers<br>

Hi, <br>
<br>
?t?p?n ?indel?? wrote a very instructive article on FastR, the GraalVM's implementation of R: <a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__medium.com_graalvm_faster-2Dr-2Dwith-2Dfastr-2D4b8db0e0dceb&d=DwMFaQ&c=RoP1YumCXCgaWHvlZYR8PZh8Bv7qIrMUB65eapI_JnE&r=CUkXBxBNT_D5N6HMJ5T9Z6rmvNKYsqupcbk72K0lcoQ&m=2cSYMkFISTzrMf6-57p1FL1aX7bcDPqGM-F6_8XZcaA&s=aJQwQL375NRJvSr4KtEtT9cablKZlq8HgP1jRj-DVIE&e=" rel="noreferrer" target="_blank">https://medium.com/graalvm/faster-r-with-fastr-4b8db0e0dceb</a> <<a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__medium.com_graalvm_faster-2Dr-2Dwith-2Dfastr-2D4b8db0e0dceb&d=DwMFaQ&c=RoP1YumCXCgaWHvlZYR8PZh8Bv7qIrMUB65eapI_JnE&r=CUkXBxBNT_D5N6HMJ5T9Z6rmvNKYsqupcbk72K0lcoQ&m=2cSYMkFISTzrMf6-57p1FL1aX7bcDPqGM-F6_8XZcaA&s=aJQwQL375NRJvSr4KtEtT9cablKZlq8HgP1jRj-DVIE&e=" rel="noreferrer" target="_blank">https://medium.com/graalvm/faster-r-with-fastr-4b8db0e0dceb</a>><br>
<br>
In which he talks about the compatibility with GNU-R, polyglot and using R from Java and Python, and some performance benchmarks. <br>
If you didn't get acquainted with FastR yet (actually even if you did look at it in the past), it's really good material to go over! <br>
