What should be spelled C-I-N-C-H is the result of inputting
Residue[1/Sinh[z],{z,I Pi}] .
This should be the same as inputting
Residue[1/(I Sin[-I z]),{z,I Pi}] .
Both inputs result in the output
Residue[Csch[z],{z, I Pi}].
To feed Mathematica the dictionary necessary to get over the hurdle,
one must input
Residue[2/(Exp[z]-Exp[-z]),{z,I Pi}].
This results in the correct output, -1.
Eeeeeeeeeeeeeekk!
