The thing I don't like with many such "pure paradigm" languages 
is not actually the fact that they stick to a single approach and 
harm the toolset. It is the fact that they define set of 
abstractions and then try to tie those to existing computer 
hardware. With modern insanely clever optimizing compilers it may 
even work performance-wise but it harms learning curve in least 
pleasant way. If language is built as bottom-up abstraction, it 
is relatively trivial to learn for someone familiar with assembly 
level. Any such language. If it is built top-down from imaginary 
abstraction set, it is always a completely new thing every time 
and you often have no idea what certain concept actually means 
(like, is "function" here really a function or some obscure 
wrapper that emulates it?)

I would favor pure FP languages much more if computers would have 
existed that operated in similar matter on hardware level but it 
does not seem like a real thing to happen ;)
