Ambiguities

The grammar contains a number of ambiguities. We hope to resolve them at some time.

• The assignment
  

  foo = bar
  

  is interpreted as the string identifier assignment. However, it can also be interpreted as making a string identifier \foo containing "bar", or a music identifier \foo containing the syllable `bar'.
• If you do a nested repeat like

  
  

  \repeat ...
  \repeat ...
  \alternative
  

  then it is ambiguous to which \repeat the \alternative belongs. This is the classic if-then-else dilemma. It may be solved by using braces.

• The parser is not sophisticated enough to distinguish at the right time between c4*2 / 3 and c4*2 / g (in chord mode).
