Slim becomes painful when using Ruby function calls (i.e. Rails helpers). Sometimes these functions have long list of parameters and wrapping to next line sometimes becomes not so convenient. Moving, copying and pasting indented blocks is also quite painful and it's much harder to see nested structure than in, for example, Python code. Also it has complicated syntax for attributes and text content, especially text content. I have to look up its docs again and again. It reminds me of yaml which has the same problems (but much worse, yaml's documentation has size of a book). However I'm not a fan of ERB or Django/Jinja template markups either. Indentation-based syntax has its advantages, it works well for Python and ML-like languages. Just Slim can be improved further.
