I have a function in a binary like this class<class1::class2>::function. I can't directly use commands like bp, u, x on the function. The only option I have right now is x class* and then look in the output for the address and then set a breakpoint bp <address>.

Is there something that I'm missing? Its too cumbersome to copy and paste addresses each debugging session. One option is to use pykd, but I am looking for a pure windbg solution.

they are supported if you add the special escape sequence @!" symbol "

make sure you set a resolved breakpoints not an unresolved one

and be aware a single address may point to several instantiations of these classes

windbg version 
Microsoft (R) Windows Debugger Version 10.0.17744.1001 X86

lets look for some functions with angle brackets in them

0:000> x /f /v windbg!*<*<*<*

prv func   00b76da9            6d windbg!Debugger::Utils::SmartCleanup_______snipped
prv func   00b76e16            46 windbg!Debugger::Utils::SmartCleanup_______snipped
pub func   00b9bcd1             0 windbg!std::basic_string<char,std::_______snipped

0:000> bp @!" windbg!Debugger::Utils::SmartCleanup_____snipped "
Bp expression '@!" windbg!Debugger::Utils::SmartCleanup<<lamb___snipped "'    

could not be resolved, adding deferred bp <<<<<

0:000> bl
     0 e Disable Clear u             0001 (0001) (@!" windbg!Debugger::Utils::SmartCleanup<<lambda_snipped

bm might help to match your function by some pattern. See this post.
